Start Learn PHP/MYSQL : How to Do Object Oriented Programming(OOP) in PHP( Easy Explained )

2023-02-17T13:28:00.010+05:30

Object-oriented programming(OOP) is a popular programming model used in present time software development. With OOP, programmers can organize code into reusable, modular components, which makes software development more efficient and easier to maintain. PHP, one of the most popular server side scripting languages,supports OOP concepts and provides developers with powerful tools to create robust and scalable applications.

In this article we will take closer look at oops in PHP and explore benefits it offers to developers.We will also discuss essential OOP concepts and how to use them in PHP programming.

What is Object-Oriented Programming.(OOP)?

Object-Oriented Programming is a programming model that focuses on creating software components that can be reused and combined to create complex/big applications.OOP is built around the concept of objects which represent real world entities or concepts. An object is a self contained unit that has properties and methods that define its behaviour.

PHP and OOP:

PHP supports OOP concepts and starting from PHP5 it provides robust support for OOP programming. OOP in PHP enables developers to create complex applications by breaking them down into smaller, reusable components. OOP in PHP allows developers to write more organized and maintainable code which is easier to debug and extend.

Object-Oriented Programming(OOP) in PHP has a large number of methods and keywords that are used to create classes,objects & methods.Here are some of most commonly used Object-Oriented Programming methods and keywords in PHP programming:

Methods:

__construct():a special method that is automatically called when an object is instantiate.
__destruct():a special method that is automatically called when an object is destroy.
__get(): a method that is called when an inaccessible property is accessed.
__set(): a method that is called when an inaccessible property is set.
__call(): a method that is called when a not accessible method is called.
static: a keyword used to define static methods and properties.
final: a keyword used to stop a class from being sub classed or a method from being overridden.
abstract: a keyword used to define abstract classes & methods.
interface: a keyword used to define interfaces.

Keywords:

class:a keyword used to define a class.
new:a keyword used to create an object instance of a class.
extends : a keyword used to define inheritance between classes.
public :a keyword used to declare a property/method as publicly accessible.
private -a keyword used to declare a property or method as accessible only within the class that defines it
protected -a keyword used to declare a property or method as accessible only within the class that defines it and its subclasses
this -a keyword used to refer to the current object instance within a class method
self - a keyword used to refer to the current class within a class method
parent - a keyword used to refer to the parent class within a class method

These are just a few of the many methods & keywords available in OOP in PHP. By understanding and using these methods and keywords effectively, you can create more powerful and efficient object-oriented code.

Essential OOP Concepts:

Classes and Objects:

Classes define the blueprint or structure of an object, while objects are instances of a class. A class is a template that defines the properties and methods of an object, while an object is a concrete realization of a class.

In PHP there are three types of classes and objects: regular classes, abstract classes and interfaces.Let's take a look at each of them and their rules.

Regular Classes Regular classes are the most common type of class in PHP and they can be instantiated to create objects.These classes can have properties and methods, which can be accessed using object notation.

Rules:

Regular classes must have a class keyword followed by a name and a set of curly braces.
Class names should follow CamelCase naming convention.
A class must be instantiated before it can be used to create objects.
Properties and methods must have an access modifier, which determines their visibility.The three access modifiers are public, protected and private.
A class can inherit from another class using the extends keyword.

Example:

PHP

< pre class="ccontentclss " >

 
 
 <?php  
 
class Car {
    public $make;
    public $model;

    public function start() {
        //code to start the car
    }

    private function checkFuel() {
        //code to check the level of  fuel 
    }
}


 ?>

Abstract Classes Abstract classes are similar to regular classes but they cannot be instantiated on their own. Instead, they are meant to be extended by other classes. Abstract classes can have abstract methods, which are methods without implementation.These methods must be implemented by any class that extends the abstract class.

Rules:

Abstract classes must have an abstract keyword before the class keyword.
An abstract class cannot be instantiated on its own.
Abstract classes can have abstract methods which are declared without an implementation.
Any class that extends an abstract class must implement all of its abstract methods.

Example:

PHP

< pre class="ccontentclss " >

 
 
 <?php  
 
abstract class Vehicle {
    public $make;
    public $model;

    abstract public function start();
}



 ?>

Interfaces Interfaces are alike to abstract classes but they can only have method signatures and constants.Any class that implements an interface must implement all of its methods. Interfaces are used to define a set of methods that must be implemented by any class that wants to use them.

Rules:

Interfaces must have an interface keyword followed by a name and a set of curly braces.
Interfaces can only have method signatures and constants not properties or method implementations.
Any class that implements an interface must implement all of its methods.

Example:

PHP

< pre class="ccontentclss " >

 
 
 <?php  
 
interface Printable {
    public function print();
}




 ?>

In summary regular classes, abstract classes and interfaces all have different rules and use cases in PHP. Regular classes are the most common and can be instantiated to create objects while abstract classes and interfaces are used for more specialized cases, such as creating blueprints for other classes or defining a set of methods that must be implemented by other classes.

Full Example of classes and objects in PHP.Imagine we are building a simple website for a library, and we want to create a class for the books that will be displayed on the site.We can create a Book class that will have properties for the title, author, and number of pages.

PHP

< pre class="ccontentclss " >

 
 
 <?php  
 
 class Book {  
   public $title;  
   public $author;  
   public $pages;  
 }  
 ?>

We can then create object of the BOOK class and set its properties...

PHP

< pre class="ccontentclss " >

 
 
 <?php  
 
$book1 = new Book();
$book1->title = "To Kill a Mockingbirds";
$book1->author = "Harry Lee";
$book1->pages = 281;

 ?>

We can also create additional objects of the BOOK class and set their properties...

PHP

< pre class="ccontentclss " >

 
  
 <?php  
 
$book2 = new Book();
$book2->title = "The Great Gat sby";
$book2->author = "F. Scott Fitz gerald";
$book2->pages = 180;

$book3 = new Book();
$book3->title = "Pride and Pre judice";
$book3->author = "Jane Aus";
$book3->pages = 279;


 ?>

We can then display the properties of each object using the echo statement.

PHP

< pre class="ccontentclss " >

 
 
 <?php  
 
echo $book1->title; // Output: To Kill a Mockingbird
echo $book2->author; // Output: F. Scott Fitzgerald
echo $book3->pages; // Output: 279



 ?>

We can also define methods with in the Book class to perform various tasks such as calculating the number of pages read per hour.

PHP

< pre class="ccontentclss " >

 
 
 <?php  
 
class Book {
    public $title;
    public $author;
    public $pages;

    public function readPagesPerHour($hours) {
        return $this->pages / $hours;
    }
}


 ?>

We can then call method on an object of the BOOK class...

PHP

< pre class="ccontentclss " >

 
 
 <?php  
 
$book1 = new Book();
$book1->title = "To Kill a Mockingbird";
$book1->author = "Harper Lee";
$book1->pages = 281;

echo $book1->readPagesPerHour(2); // Output: 140.5

 ?>

As you can see classes and objects in PHP provide a powerful way to encapsulate data and logic in reusable components. By defining a class, we can create multiple instances of that class (i.e.objects) with their own unique properties and methods.This makes our code more modular and easier to maintain as well as more efficient and scalable.

Encapsulation:

Encapsulation is a mechanism that hides the internal details of an object and exposes only the necessary information. It ensures that the data inside an object is not accessible from outside the object. It is an important concept in Object-Oriented Programming(OOP) that allows you to hide the implementation details of a class from the outside world.This helps to prevent accidental modification of class properties and methods and ensures that they are only accessed and modified in a controlled way. In PHP,encapsulation can be achieved using access modifiers such as public, private and protected.

Public:
Public properties and methods are accessible from anywhere in the code both inside and outside of the class. This means that they can be accessed by objects, functions, and other classes.

Private :
Private properties and methods are only accessible from with in the class. They cannot be accessed by objects functions or other classes outside of the class. This means that the value of a private property can only be set or retrieved by methods within the same class.

Protected :
Protected properties and methods are only accessible from within the class and its subclasses. This means that they cannot be accessed by objects or functions outside of the class but they can be accessed by subclasses that inherit from the class.

Here example of Encapsulation in PHP:

PHP
< pre class="ccontentclss " > `<?php class BankAccount { private $balance; public function deposit($amount) { $this->balance += $amount; } public function withdraw($amount) { if ($amount <= $this->balance) { $this->balance -= $amount; } else { echo "Insufficient funds"; } } public function getBalance() { return $this->balance; } } ?>`

In this example, we define a Bank Account class with a private property $balance and three methods: deposit(), withdraw()and `getBalance(). The deposit() method allows a user to add money to their account, while the withdraw() method allows them to remove money from their account. The getBalance() method allows them to check their current account balance.`
Note that the $balance property is marked as private, which means that it can only be accessed within the class itself. This ensures that the balance can only be modified by the deposit() and withdraw() methods, and cannot be accessed or modified directly from outside the class. This helps to prevent accidental modification of the balance and ensures that it is only accessed and modified in a controlled way. Here an example of how to use the Bank Account class: PHP < pre class="ccontentclss " > <?php $account = new BankAccount(); $account->deposit(1000); $account->withdraw(500); echo "Acc Balance: " . $account->getBalance(); ?> In this example we create a new Bank Account object, deposit 1000 into the account, withdraw 500 from the account, and then print the current balance using the getBalance() method. Note that we can only access the balance using the getBalance() method, and cannot modify it directly. By encapsulating the balance property and only allowing it to be accessed and modified through controlled methods, we can ensure that the account balance is always accurate and that it cannot be accidentally modified or tampered with.

`Inheritance:`

Inheritance is a mechanism that enables one class to inherit properties and methods from another class. Inheritance promotes code reuse, and it simplifies the design and maintenance of complex applications.It is a powerful feature in Object-Oriented Programming (OOP) that allows you to create new classes that are based on existing classes, inheriting their properties and methods. In PHP, you can use the extends keyword to create a subclass that inherits from a parent class.


    Here example of inheritance in PHP:
     
 
  
               PHP  
  
  < pre class="ccontentclss " >
 
 
   
 <?php  
 
 class Animal {  
     protected $name;  
   protected $color;  
   
   public function __construct($name, $color) {  
          $this->name = $name;  
     $this->color = $color;   
  }  
   
   public function eat() {  
               echo  "{$this->name}    eating...";     }  
 }  
   
 class Dog extends Animal {  
   public function bark() {  
     echo  "{$this->name}    barking...";   } 
 }  

 ?>  
  


    In this example we define an Animal class with two protected properties ($name and $color) and a eat() method. We then define a Dog class that extends the Animal class, and adds a bark() method.
    

Note that the Dog class uses the extends keyword to inherit from the Animal class.This means that the Dog class will have access to all of the properties and methods of the Animal class, as well as its own bark() method.
     Here example of how to use the Dog class:
    
 
  
               PHP  
  
  < pre class="ccontentclss " >
 
  
 <?php  
 
$dog = new Dog('Fido', 'Brown');
$dog->eat(); //  Output: Fido eating...
$dog->bark(); //  Output: Fido  barking...
 

 ?>  
  

    In this example we create a new DOG object and pass in a name and color to its constructor.We then call its eat() and bark() methods which were inherited from the Animal class and defined in the Dog class respectively.
    By using inheritance we can create new classes that are based on existing classes inheriting their properties and methods and adding new functionality. This allows us to write more efficient and reusable code and makes it easier to organize and maintain our programs
    
  Polymorphism: 
    Polymorphism is the ability of an object to take on different forms or behaviors. In PHP, polymorphism is achieved through method overriding and method overloading.It is an important concept in Object-Oriented Programming (OOP) that allows objects of different classes to be treated as if they were the same type. This is achieved by using inheritance and method overriding, which allows a subclass to provide its own implementation of a method that is already defined in its parent class. In PHP, polymorphism can be achieved using the extends keyword and the override keyword.
    Here example of polymorphism in PHP:
    
 
  
               PHP  
  
  < pre class="ccontentclss " >
 
 
 <?php  
 
 class Shape
 {  
   public function getArea() 
{  
     return 0;  
   }  
 }  
   
 class Circle extends  Shape
 {  
   private $radius;  
   
   public function __construct($radius) 
{  
     $this->radius = $radius;  
 }  
   
   public function getArea()
 {  
     return 3.14 * $this->radius * $this->radius;  
               }  
 }  
   
 class Square extends Shape {  
   private $length;  
   
   public function __construct($length){  
     $this->length = $length;  
                           }  
   
   public function getArea() 
{  
     return $this->length * $this->length;     }  
 }  

 ?>  
  

    In this example we define a Shape class with a getArea() method that returns 0.We then define two subclasses: Circle and Square, both of which extend the Shape class and provide their own implementation of the getArea() method. 
 

Note that the getArea() method is defined in the Shape class and overridden in the Circle and Square classes. This allows objects of the Circle and Square classes to be treated as if they were objects of the Shape class because they share the same method signature.
 
 
Here example of how to use the Shape, Circle, and Square classes: 
   
 
  
               PHP  
  
  < pre class="ccontentclss " >
 
 
 <?php  
 
  $shapes = array(  
   new Circle(5),  
   new Square(4),  
   new Circle(3)  
 );  
   
 foreach ($shapes as $shape){  
   echo "Area: " . $shape->getArea() . "<br>";  
 }  
 ?>  
  

    In this example we create an array of Shape objects that contains two Circle objects and one Square object. We then iterate over the array and call the getArea() method on each object which will call the appropriate implementation of the method in each subclass.
    By using polymorphism we can write more flexible and extensible code that can be easily adapted to different situations. This allows us to write code that is more maintainable, reusable and efficient and makes it easier to add new functionality to our programs.
    
    Abstraction: 
    Abstraction is a mechanism that allows developers to create generalized models of realworld entities / concepts. It helps to reduce complexity and increase the reusability of code.It is an important concept in Object-Oriented Programming (OOP) that allows us to hide the implementation details of a class from its users, while still providing a clear and concise interface for interacting with that class. In PHP we can achieve abstraction by using abstract classes and abstract methods.
    Here example of abstraction in PHP:
     
 
  
               PHP  
  
  < pre class="ccontentclss " >
 
 
 <?php  
 
 abstract class  Shape {  
   protected $color;  
   
   public function __construct($color)   {  
     $this->color = $color;  
   }  
   
   public function getColor() {  
     return  $this->color;  
   }  
   abstract public function getArea();  
 }  
 
 class Circle extends Shape {  
   private $radius;  
   public function __construct($color, $radius)
 {  
     parent::__construct($color);  
     $this->radius = $radius;  
 }  
   public function getArea() {  
     return 3.14 * $this->radius * $this->radius; 
}  
 }  
 class Square extends Shape {  
   private   $length;  
   public function __construct($color, $length) {  
     parent::__construct($color);  
     $this->length = $length;  
   }     
   public function getArea() {  
     return $this->length * $this->length;  
   }  
 }  
   
 ?>  
  

    In this example we define a Shape class with a getArea() method that returns 0. We then define two subclasses: Circle and Square, both of which extend the Shape class and provide their own implementation of the getArea() method.
    

Note that the getArea() method is defined in the Shape class and overridden in the Circle and Square classes. This allows objects of the Circle and Square classes to be treated as if they were objects of the Shape class because they share the same method signature.
    

Here example of how to use the Shape, Circle and Square classes:
    
    
   
 
  
               PHP  
  
  < pre class="ccontentclss " >
 
 
 <?php  
 
$shapes = array(
    new Circle(5),
    new Square(4),
    new Circle(3)
);
foreach ($shapes as $shape) {
    echo "Area : " . $shape->getArea() . "
";
}

 ?>  
  

   In this example We create an array of Shape objects that contains two Circle objects and one Square object.We then iterate over the array and call the getArea() method on each object which will call the appropriate implementation of the method in each subclass.
    

By using polymorphism we can write more flexible and extensible code that can be easily adapted to different situations.This allows us to write code that is more maintainable, reusable and efficient and makes it easier to add new functionality to our programs.



Benefits of OOP in PHP:
Reusability :OOP in PHP enables developers to write reusable code, which reduces development time and increases efficiency.
  Modularity: OOP in PHP allows developers to break down complex applications into smaller manageable components.This improves the organization of code and makes it easier to maintain and debug. 
  Extensibility: OOP in PHP promotes the use of inheritance and polymorphism which allows developers to extend the functionality of existing code without modifying the original code.
 Security: O O P in PHP enables developers to implement secure coding practices such as encapsulation and data hiding which helps to protect sensitive data from unauthorized access.

OOP in PHP is a powerful programming paradigm that enables developers to create scalable, efficient and maintainable applications. The essential OOP concepts in PHP including classes and objects, encapsulation, inheritance, polymorphism and abstraction, make it possible to create reusable, modular and secure code. By understanding the benefits of OOP in PHP developers can write better quality code that is easier to maintain and extend.



Start Learn PHP/MYSQL : How to Do PHP Development and MySQL Database Connectivity A Complete Guide for Beginners
2023-02-16T17:31:00.009+05:30
 If you are interested in building web applications and working with databases but do not know where to start you have come to the right place. In our previous articles we have covered topics likePHP and MySQL setup for Windows and Linux OS. Today we will dive into the basics of PHP. As a powerful and versatile programming language, PHP is widely used for developing dynamic web applications, handling files and connecting to databases.By mastering its fundamentals you can take your web development skills to the next level.

In this guide we will focus specifically on the basics of PHP web development and database connectivity. From variables and data types to operators, control structures and functions we will cover everything you need to know to get started with PHP.With real world examples and best practices we will guide you through the process of connecting PHP to a database and working with common database operations like reading, writing and updating data.

Whether you are a beginner or have some experience with other programming languages this guide will provide a solid foundation for building your skills in PHP and developing your own web applications.So let's Get started and learn the basics of web development and database connectivity in PHP to become a proficient web developer .
Here are some of the basics of PHP:
Syntax: PHP code is typically embedded within HTML, using opening and closing tags respectively. PHP statements end with a semicolon (;).
  

Variables: In PHP you can define variables using the $ symbol, followed by the variable name. For example, $name = "John"; assigns the value "John" to the variable $name.

Data Types: PHP has various data types, including strings, integers, floats, booleans, arrays and objects.

Operators: PHP has various operators including arithmetic (+, -, *, /, %), assignment (=), comparison (==, !=, >, <, >=, <=), and logical (&&, ||, !).

Control Structures: PHP has various control structures, including if-else statements, switch statements, while and do-while loops ,for loops and foreach loops.

Functions: PHP allows you to define and call functions. Functions are used to perform specific tasks and can be reused throughout your code.

Forms: PHP is commonly used in web development to process data submitted through HTML forms.
1.Syntax:
 PHP is a server side scripting language which means that the code is executed on the server before the resulting HTML is sent to the client's browser. PHP code is typically embedded within HTML using opening and closing tags respectively.Here is an example of PHP code that prints "Hello world!" to the screen:

  
    PHP 
  
   <!DOCTYPE html>  
 <html>  
 <body>  
   
 <?php  
 echo "Hello world!";  
 ?>  
   
 </body>  
  </html> 


In Example echo statement is used to print the text  "Hello world !"  to the screen. 
get started with running PHP code on your PC the first step is to run XAMPP controller .This will allow you to run PHP code on your computer/PC. Once XAMPP is running navigate to the C > xampp > htdocs folder on your PC. In this folder create a new folder called "test".Next create a new file in this folder called "index.php". You can open this file in a plain text editor like notepad or you can download a more advanced editor like Sublime & Visual Studio .

After opening the "index.php" file in your text editor copy the PHP code from above and paste it into the file. Save the file  close the editor. You re now ready to run your first PHP Code .

To do this open your web browser (such as Google Chrome/ Internet Explorer)and enter the following URL in the address bar:"localhost/test/index.php". This will run the PHP code and display the message "Hello world!" in your web browser .

Congratulations you have successfully Run your first PHP code on your PC/Computer.With this basic setup you can now begin to learn more about PHP  and Start building your own web applications .



2.Variables:
In PHP variables re used to store values.Variables can be assigned a value using the $ symbol followed by the variable name . Example :

  
    PHP 
  
   <!DOCTYPE html>  
 <html>  
 <body>  
   
 <?php  
 $name = "John";  
 $age = 30;  
 $height = 1.75;  
 $is_student = true;  
 ?>  
     
 <?php echo $name; ?><br>  
 <?php echo $age; ?><br>  
 <?php echo $height; ?><br>  
 <?php echo $is_student; ?>  
   
  
 </body>  
 </html>   


In this example four variables are defined: $name, $age, $height and $is_student. The variable $name is assigned the value "John" $age is assigned the value 30 $height is assigned the value 1.75 and $is_student is assigned the value true. Note that PHP is a loosely typed language, which means that the data type of a variable is determined automatically based on the value assigned to it.



3.Data Types:
PHP has several data types including:

Strings: a sequence of characters enclosed in quotes. Example : "Hello world!"

Integers: whole numbers without a decimal point. Example: 42

Floats: numbers with a decimal point. Example: 3.14

Booleans: true or false. Example: true

Arrays: a collection of values indexed by a key. Example: $colors = array("red", "green", "blue");

Objects: a complex data type that represents a realworld object. 

Example:


  
    PHP 
  
   <!DOCTYPE html>  
 <html>  
 <body>  
   
 <?php  
 $name = " John ";  
 $age = 30;  
 ?>  
     
 <?php echo " Hello my name is $name and I m $age years old . "; ?>  
   
   
   
 </body>  
 </html>  
In the above code , we define two variables using PHP.$name is a string datatype and is assigned the value "John" while $age is an integer datatype and is assigned the value 30. Using the echo statement we print a greeting to the screen that includes the values of these variables. The output of the code will be "Hello , my name is John and I am 30 years old". This simple example demonstrates how to define variables and output their values using PHP.
4.Operators:

PHP has several operators  including:
1.Arithmetic operators: used to perform mathematical operations , such as addition (+), subtraction (-), multiplication (*), division (/) and modulus (%) .

  
    PHP 
  
    <!DOCTYPE html>  
 <html>  
 <body>  
 <?php  
 $x = 10;  
 $y = 3;  
 echo $x + $y;    //Outputs 13  
 echo $x - $y; // Outputs 7  
 echo $x * $y; //Outputs 30  
 echo $x / $y; // Outputs 3.3333333333333  
 echo $x % $y; // Outputs 1  
 ?>  
   
   
   
 
 </body>  
 </html>  

2.Assignment operators : used to assign a value to a variable . Example:

  
    PHP 
  
    <!DOCTYPE html>  
 <html>  
 <body>  
   
 <?php  
 $x = 10;
 $y = 3;
 $x += $y;  // equivalent to  $x = $x + $y;
 $x -= $y;   //  equivalent to $x = $x - $y;
 $x *= $y; // equivalent to $x = $x * $y;
 $x /= $y; //  equivalent to $x = $x / $y;
 $x %= $y; // equivalent to $x = $x % $y;
 ?>  
   
   
   
   
 </body>  
 </html>  

3.Comparison operators : used to compare two values . Example:

  
    PHP 
  
    <!DOCTYPE html>  
 <html>  
 <body>  
   
 <?php  
  $x = 10;  
  $y = 3;  
  var_dump($x == $y); // Outputs bool(false)  
  var_dump($x != $y); // Outputs bool(true)  
  var_dump($x > $y); // Outputs bool(true)  
  var_dump($x < $y); // Outputs bool(false)  
  var_dump($x >= $y); // Outputs bool(true)  
  var_dump($x <= $y); // Outputs bool(false)  
 ?>  
   
   
   
   
 </body>  
 </html>  

4.Logical operators : used to combine two or more conditions . Example:

  
    PHP 
  
    <!DOCTYPE html>  
 <html>  
 <body>  
   
 <?php  
  $x = 10;  
 $y = 3;  
 $z = 5;  
 var_dump($x > $y && $x > $z); // Outputs bool(true)  
 var_dump($x > $y || $x < $z); // Outputs bool(true)  
 var_dump(!($x > $y)); // Outputs bool(false)   
 ?>  
   
   
   
   
 </body>  
 </html>  

5.Control Structures:

Control Structures In PHP  re Used to execute code based on certain conditions . 
If-else statements : used to execute code if a certain condition is true or execute a different code if the condition is false. Example:

  
    PHP 
  
    <!DOCTYPE html>  
 <html>  
 <body>  
   
 <?php  
 $x = 10;
$y = 3;
if ($x > $y) {
  echo "x is greater than y";
} else {
  echo "x is less than or equal to y";
}  
//Outputs x is greater than y
 ?>  
   
   
   
   
 </body>  
 </html>  


Switch statements : used to execute different code blocks based on the value of a variable . Example:

  
    PHP 
  
    <!DOCTYPE html>  
 <html>  
 <body>  
   
 <?php  
$day = "Monday";
switch ($day) {
  case "Monday":
    echo "Today is monday";
    break;
  case "Tuesday":
    echo "Today is tuesday";
    break;
  case "Wednesday":
    echo "Today is wednesday";
    break;
  default:
    echo "Today is not monday, tuesday or wednesday";
} 
//Outputs Today is monday
 ?>  
   
   
   
   
 </body>  
 </html>  

Loops: used to execute a block of code multiple times . Here are some examples:

  
    PHP 
  
    <!DOCTYPE html>  
 <html>  
 <body>  
   
<?php  
 // While loop  
 $i = 1;  
 while ($i <= 10) {  
  echo $i;  
  $i++;  
 }  
 ?>  //Outputs 12345678910
 <br> <?php  
 // Do-while loop  
 $i = 1;  
 do {  
  echo $i;  
  $i++;  
 } while ($i <= 10);  
   
 // For loop  
 for ($i = 1; $i <= 10; $i++) {  
  echo $i;  
 }  
 ?>  //Outputs 1234567891012345678910
 <br><?php  
 // Foreach loop (used to loop through arrays)  
 $colors = array("Red", "Green", "Blue");  
 foreach ($colors as $color) {  
  echo $color;  
 }  
 ?>  //Outputs RedGreenBlue
    


   
   
   
   
 </body>  
 </html>  


6.Functions:

Functions in PHP are used to perform specific tasks and can be reused throughout your code. Here 's an example of a function that calculates the sum of two numbers :


  
    PHP 
  
    <!DOCTYPE html>  
 <html>  
 <body>  
   
 <?php  
function sum($x, $y) {
  $result = $x + $y;
  return $result;
}

echo sum(2, 3); 

 ?>  // Outputs 5
   
   
   
   
 </body>  
 </html>  

In this example a function called 'sum ' is defined that takes two parameters $x and $y calculates their sum and returns the result using the return statement. The function is then called with the arguments 2 and 3 and the result is printed using the echo statement.

Functions can also have default parameter values which are used if no value is passed in for that parameter:


  
    PHP 
  
   <!DOCTYPE html>  
 <html>  
 <body>  
   
 <?php  
function sayHello($name = "World") {
  echo "Hello, $name!";
}

sayHello(); 
sayHello("John"); 

 ?>  // Outputs "Hello World!" 
 // Outputs "Hello John!" 
   
   
   
   
 </body>  
 </html>  
In this example a function called sayHello is defined that takes an optional parameter $name with a default value of "World" . If a value is passed in for $name that value is used , otherwise the default value is used. The function is then called twice once with no argument and once with the argument "John" , and the output is printed using the echo statement.

7.Arrays:

Arrays in PHP are used to store multiple values in a single variable. Here 's an example of an array:

  
    PHP 
  
    <!DOCTYPE html>  
 <html>  
 <body>  
   
 <?php  
$colors = array("red", "green", "blue");
echo $colors[0]; // Outputs "red"
echo $colors[1]; // Outputs "green"
echo $colors[2]; // Outputs "blue"

 ?>  
   
   
   
   
 </body>  
 </html>  

In this example an array called $colors is defined that contains three elements . The elements are accessed using their index , which starts at 0.

  Arrays can also be created using the array function :

  
    PHP 
  
    <!DOCTYPE html>  
 <html>  
 <body>  
   
 <?php  
$ages = array("Peter" => 32, "John" => 28, "Mary" => 45);
echo $ages["John"]; // Outputs 28

 ?>  
   
   
   
   
 </body>  
 </html>  

In this example an array called $ages is defined using key-value pairs . The elements are accessed using their key which is a string .

  Arrays can be looped through using the foreach loop :

  
    PHP 
  
    <!DOCTYPE html>  
 <html>  
 <body>  
   
 <?php  
$colors = array("red", "green", "blue");
foreach ($colors as $color) {
  echo $color;
}
// Outputs RedGreenBlue
 ?>  
   
   
   
   
 </body>  
 </html>  

In this example the array $colors is looped through using the foreach loop and each element is printed using the echo statement.

8.File Handling:
File handling in PHP is used to read and write files on a server . The fopen function is used to open a file and returns a file pointer that is used to access the file. Here 's an example of reading a file: Create a new file and name it "example.txt".Type "Hello World My name is Jhon" into the file and save the file . 

  
    PHP 
  
    <!DOCTYPE html>  
 <html>  
 <body>  
   
 <?php  
$file = fopen("example.txt", "r");
if ($file) {
  while (($line = fgets($file)) !== false) {
    echo $line;
  }
  fclose($file);
}
// Outputs Hello World My name  is Jhon
 ?>  
   
   
   
   
 </body>  
 </html>  

 
In this example  the fopen function is used to open a file called example.txt in read mode . The while loop is used to read each line of the file using the fgets function and output it using the echo statement. Finally the fclose function is used to close the file .

  writing to a file is also possible Using the  fopen function in write mode :

  
    PHP 
  
    <!DOCTYPE html>  
 <html>  
 <body>  
   
 <?php  
$file = fopen("example.txt", "w");
fwrite($file, "Hello World!");
fclose($file);
 ?>  
   
   
   
   
 </body>  
 </html>  


In this example, the fopen function is used to open a file called example.txt in write mode. The fwrite function is used to write the string "Hello World!" to the file, and the fclose function is used to close the file.
9. Database Connectivity:
PHP is often used for web development, and it 's common to interact with databases to store and retrieve data. PHP provides several extensions to interact with databases including MySQL and PostgreSQL.
In a previous post about MySQL, we discussed how to create a database and table. In this post we will provide a summary of those steps and explain how to create a database using phpMyAdmin .
In this post we will explain how to create a database using phpMyAdmin which is a popular webbased tool for managing MySQL databases. With phpMyAdmin you can easily create and manage databases , tables and other database objects.
You can create a new database by following these Steps:
Click on the "New" button in the left hand navigation menu to create a new database.
Enter a name for your database in the "Create database" form.You can choose any name you like but it ' s a good idea to choose something descriptive and easy to remember.
Select the default collation for your database. This specifies the character set and sorting order that should be used for text data in your database. In most cases , you can leave this set to the default value of "utf8_general_ci".
Click the "Create"  button to create your new database.
Once you have created your database , you can start creating tables by following these steps:
Click on the name of the database you just created to enter it.
Click on the "New" button in the left  hand navigation menu to create a new table.
  Enter a name for your table in the "Create table" form. Again , it 's a good idea to choose a descriptive name that reflects the purpose of your table.
Enter the number of Columns you want your table to have.Each column represents a different Type of data that you want to store in the table.
For each column, enter a name and select a data type. The data type determines the kind of data that can be stored in the column. For example , you might use an "int" data type for numeric values or a "varchar" data type for text strings.
You can also specify additional options for each column, such as whether it should be a primary key (which uniquely identifies each row in the table), or whether it should have a default value or be set to auto-increment.
Once you have defined all of your columns and their options, click the "Save" button to create your new table.
That's it! You have now created a new database and table using phpMyAdmin. From here, you can start populating your table with data, running queries and managing your database in a variety of other ways.
To create a table named "users" with three columns - "id", "name" and "email" - using phpMyAdmin, you can follow these steps:
Open phpMyAdmin and select the database where you want to create the "users" table.You can select the database by clicking on its name in the left-hand sidebar.
Click on the "Structure" tab at the top of the page to create a new table.
In the "Create table" section, enter "users" in the "Table name" field.
Under "Number of columns" , enter "3".
In the first row of the "Column name" column, enter "id".
In the "Type" column for the "id" column select "INT" for integer.
Check the "A.I." (Auto Increment) checkbox to make the "id" column an autoincrementing field.
In the "Attributes" section for the "id" column, select "Primary" to make it the primary key of the table.
Repeat steps 5-8 for the "name" and "email" columns.
Click on the "Save" button at the bottom of the page to create the "users" table with the specified columns.
That 's it! You have now successfully created a new table named "users" with three columns using phpMyAdmin. You can now start populating the table with data by using the "Insert" tab in phpMyAdmin or by using SQL statements to insert data directly into the table.
Insert query
To insert data into the "users" table using SQL queries in PHP You can use The following code :

  
    PHP 
  
    <!DOCTYPE html>  
 <html>  
 <body>  
   
 <?php  
 $servername = "localhost";  
 $username = "username";  
 $password = "";  
 $dbname = "myDataB";  
   
 // Create connection  
 $conn = new mysqli($servername, $username, $password, $dbname);  
   
 // Check connection  
 if ($conn->connect_error) {  
  die("Connection failed: " . $conn->connect_error);  
 }  
   
// Insert data into the table
$sql = "INSERT INTO users (name, email) VALUES ('John', 'john@example.com')";
if ($conn->query($sql) === TRUE) {
    echo "New record created successfully";
} else {
    echo "Error: " . $sql . "
" . $conn->error;
}
   
 // Close connection  
 $conn->close();  
 ?>    
   
   
   //Outputs new record created successfully
   
 </body>  
 </html>  

This  code creates a new connection to your MySQL database using the connection variables (servername, username, password, dbname), and then inserts a new record into the "users" table with the values "John " for the "name" column and "john@example.com" for the "email" column.
SELECT query

  Here 's an example of connecting to a MySQL database and executing a query:

  
    PHP 
  
    <!DOCTYPE html>  
 <html>  
 <body>  
   
 <?php  
 $servername = "localhost";  
 $username = "username";  
 $password = "";  
 $dbname = "myDataB";  
   
 // Create connection  
 $conn = new mysqli($servername, $username, $password, $dbname);  
   
 // Check connection  
 if ($conn->connect_error) {  
  die("Connection failed: " . $conn->connect_error);  
 }  
   
 // Execute query  
 $sql = "SELECT * FROM users";  
 $result = $conn->query($sql);  
   
 // Output results  
 if ($result->num_rows > 0) {  
  while ($row = $result->fetch_assoc()) {  
   echo "Name: " . $row["name"] . " - Email: " . $row["email"];  
  }  
 } else {  
  echo "0 results";  
 }  
   
 // Close connection  
 $conn->close();  
 ?>    
   
     //Outputs Name: John - Email: john@example.com
   
   
 </body>  
 </html>  

In this Example, a connection to a MySQL database is established using the mysqli extension. The connect_error property is used to check if the connection was successful.The query method is used to execute a SQL query, and the fetch_assoc method is used to retrieve each row of the result set. Finally , the close method is used to Close the connection.

UPDATE query
To update an existing record in the "users" table using an SQL query in PHP  you can use the following code as an example:

  
    PHP 
  
    <!DOCTYPE html>  
 <html>  
 <body>  
   
 <?php  
 $servername = "localhost";  
 $username = "username";  
 $password = "";  
 $dbname = "myDataB";  
   
 // Create connection  
 $conn = new mysqli($servername, $username, $password, $dbname);  
   
 // Check connection  
 if ($conn->connect_error) {  
  die("Connection failed: " . $conn->connect_error);  
 }  
   
 // Update record in the table
$sql = "UPDATE users SET name='Jane Ross', email='jane.ross@example.com' WHERE id=1";
if ($conn->query($sql) === TRUE) {
    echo "Record updated successfully";
} else {
    echo "Error updating record: " . $conn->error;
}
   
 // Close connection  
 $conn->close();  
 ?>    
   
     //Outputs record updated successfully
   
   
 </body>  
 </html>  

In this Example , the code connects to the MySQL database using the connection variables (servername, username, password , dbname)  and then updates the record with an "id" value of 1 in the "users" table to set the "name" to "Jane Ross" and The "email" to "jane.ross@example.com" .

You can modify the sql query to update different records in the table with different values.You can use various SQL operators and conditions to specify which records you want to update. For Example , you can use the WHERE clause to Specify a condition that must be met for the record to be updated .

DELETE query
To delete a record from the "users" table using an SQL query in PHP  you can use the following code as an example :

  
    PHP 
  
    <!DOCTYPE html>  
 <html>  
 <body>  
   
 <?php  
 $servername = "localhost";  
 $username = "username";  
 $password = "";  
 $dbname = "myDataB";  
   
 // Create connection  
 $conn = new mysqli($servername, $username, $password, $dbname);  
   
 // Check connection  
 if ($conn->connect_error) {  
  die("Connection failed: " . $conn->connect_error);  
 }  
   
 // Delete record from the table
$sql = "DELETE FROM users WHERE id=1";
if ($conn->query($sql) === TRUE) {
    echo "Record deleted successfully";
} else {
    echo "Error deleting record: " . $conn->error;
}
 // Close connection  
 $conn->close();  
 ?>    
   
     //Outputs record deleted successfully
   
   
 </body>  
 </html>  

In this Example , the code connects to the MySQL database using the connection variables (servername, username, password , dbname), and then deletes the record with an "id" value of 1 from the "users" table.

You can modify the SQL query to delete different records from the table based on different conditions. For example  you can use the WHERE clause to specify a condition that must be met for the record to be deleted .

Exploring the Rise of Remote Work and Freelancing : Impacts, Benefits and Challenges
2023-02-13T11:56:00.003+05:30
The COVID19 pandemic has dramatically altered the way people work. With millions of employees around the world forced to work from home to help slow the spread of the virus, remote work has become a necessity for many businesses.As the pandemic continues to evolve, the trend toward remote work is likely to persist and even accelerate shaping the future of work for years to come.

Remote work also known as telecommuting or telework, has been around for decades. However, it has only been in recent years that it has become a widely adopted form of work. According to a study by Global Workplace Analytics remote work has grown by 140% since 2005 and it has accelerated dramatically since the start of the COVID19 pandemic.

One of the main drivers of the rise of remote work is the rapid advancement of technology.The widespread availability of highspeed internet, cloud computing and collaboration tools has made it easier than ever for employees to work from anywhere. Additionally the rise of the gig economy and the increasing number of self employed workers has further contributed to the trend.

The benefits of remote work are numerous. For employees remote work can provide more flexibility and a better work life balance. It allows employees to avoid the daily commute, saving them time and money.Additionally remote work can also lead to increased productivity as employees are able to work in a more comfortable and familiar environment.


For employers remote work can provide access to a wider pool of talent as they are no longer limited to hiring employees who live in the same location as their office.It can also lead to reduced overhead costs as there is no need to maintain a physical office space. Furthermore remote work can increase employee satisfaction and reduce turnover as employees are able to work in a way that suits them best.

Despite the benefits remote work is not without its challenges. One of the biggest challenges is the potential for isolation and loneliness as remote workers may feel disconnected from their colleagues and the workplace culture. Additionally remote work can also lead to difficulties with communication and collaboration as employees are not in the same location to work together in person.

To overcome these challenges it is important for remote workers to stay connected to their colleagues and the workplace culture. This can be done through the use of virtual collaboration tools, regular video calls, and virtual team building activities. Additionally remote workers should also make an effort to maintain a healthy work life balance as it is easy to blur the lines between work and personal time when working from home.

As the trend toward remote work continues to grow it is likely to have a significant impact on the future of work.Remote work is likely to become the norm for many businesses as employers recognize the benefits and over come the challenges. Additionally the rise of remote work may also lead to the creation of new job opportunities as businesses seek to hire remote workers to fill specific roles .

One of the areas that is likely to be greatly impacted by the rise of remote work is freelancing. Freelancing has been growing rapidly in recent years and the trend is likely to accelerate as remote work becomes more widespread. Freelancing offers a number of benefits including the ability to work from anywhere flexible hours and the ability to choose projects that match one 's skills and interests.

There are numerous websites that connect freelancers with clients who are looking for their services. Some of the most popular freelancing websites include Upwork,Fiverr and Freelancer. These websites make it easy for freelancers to find work as clients can post projects and receive bids from freelancers around the world .

The rise of remote work has also led to the growth of remote job websites. These websites connect job seekers with employers who are looking for remote workers. Some of the most popular remote job websites include Remote.co,FlexJobs and We Work Remotely.These websites provide job seekers with access to a wide range of remote job opportunities in industries such as tech, finance and marketing .

Remote job websites make it easy for job seekers to find remote work that matches their skills and interests. They can search for jobs based on location, job type and salary, and apply for jobs with just a few clicks. Additionally many remote job websites also offer resources and support for job seekers including resume building tips and interview preparation guidance.

While the trend toward remote work and the rise of remote job websites are certainly exciting it is important to note that remote work is not for everyone. Some people may find it difficult to work from home as they may feel lonely or disconnected from their colleagues. Additionally remote work may also lead to difficulties with boundaries and work life balance, as it can be difficult to separate work and personal time when working from home.

Despite these challenges the trend toward remote work is likely to persist and even accelerate in the coming years.As technology continues to advance and more businesses adopt remote work remote jobs are likely to become more common and indemand. Freelancers and remote workers will play a key role in shaping the future of work as they continue to drive innovation and growth in the digital economy.

One of the biggest benefits of remote work and freelancing is the ability to work from anywhere in the world.With the rise of remote jobs people are no longer limited by geography and can work from anywhere that has an internet connection.This gives people the freedom to work from home, travel or even move to a different country while still being able to earn a living.

Another benefit of remote work and freelancing is the increased flexibility and control over one's work schedule. Remote workers and freelancers often have more control over their work hours which can help them to achieve better work life balance and avoid burnout. In addition remote work and freelancing can also offer a more flexible and cost effective way to start a business as there is no need for a physical office space and lower overhead costs .

However it is also important to note that remote work and freelancing come with their own unique set of challenges. For example, remote workers and freelancers may struggle with isolation and lack of social interaction and they may also have difficulty separating work and personal time. Additionally there are also challenges related to job security and benefits as remote workers and freelancers may not have access to the same benefits and protections as traditional employees.

Despite these challenges the future of work is rapidly changing, and remote jobs and freelancing are becoming an increasingly popular choice for people around the world. As technology continues to advance and more businesses embrace remote work the demand for remote jobs and freelancers is only likely to grow. Whether you are a job seeker looking for new opportunities or a business looking to hire the best talent the future of work is full of possibilities and opportunities.

The future of work is rapidly changing, and the rise of remote jobs is a key part of this transformation. With the growth of remote work and the rise of remote job websites the opportunities for freelancers and remote workers are vast and exciting.Whether you are a job seeker looking for new opportunities or a business looking to hire the best talent the future of work is bright and full of possibilities .


Google AI bard Chatbot's one Wrong Answer Wipes Out $120 bn: Alphabet's Share Price Drops by 8%(NEWS)
2023-02-10T13:36:00.005+05:30
Google's AI chatbot Bard Causes Market Crash 8% : 
    
More than $120 bn was wiped off Google ’s market value after its new AI search assistant gave one wrong answer that was featured in promotional material.
   Parent company Alphabet ’ s share price dropped by 8 pc after the Google Bard tool’ s launch got off to a rocky start following its misleading response to a question about a NASA telescope.
   At its lowest point on Wednesday Alphabet was trading at $98.08 (£81.16) a fall of 8.1 pc on the previous day’ s price of $ 106.77 (£88.35).
    It marked the biggest one-day fall in Alphabet’ s value since October 2022,when the company shed 9pc of its value in one day after unveiling a big slowdown in sales,profits and growth.
    Google bard -The AI Search  assistant 
    Bard, its AI search assistant , is used by google to generate text summaries of search results .
   Yet in an animated image of Google Bard in action distributed by the company to mark the new feature’ s launch , it gives a wrong answer.
    The falsehood will raise further  questions about the accuracy of search engines and of AI  generated answers to humans questions .
    Wrong  Answer Raises Concerns About AI Accuracy
    In an animated GIF showing how Bard works, a user types in the search query “what new discoveries from the James Webb Space Telescope can I tell my 9 year old about?”

    The Nasa telescope was made operational in december 2021 and has been used  by  scientists to make several discoveries of new  planets outside the our Solar System .
       One of the responses generated by Bard says : " JWST took the very first pictures of a  planet outside of our own solar  system." 
    This is not accurate. The first picture ever taken of a planet outside the solar system an exoplanet  was captured in 2004 by the Very Large Telescope array in Chile.
    The exo planet is called 2M1207b is around  five times The size of Jupiter and  is located about 170 light years of away from Earth .
    Fears have been raised about  inaccuracies generated by  Artificial intelligence systems which are not easily spotted by the humans .
   Chat Bot Rival OpenAI Admits Limitations of Technology
     OpenAI makers of chatbot rival ChatGPT have been open about the limitations of their technology and have admitted it can sometimes write plausible sounding but incorrect, or nonsensical , answers to humans questions .
    The company is owned by Microsoft , whose share price has grown 6 pc over the past week. Market analysts believe its recent growth is down to the launch of ChatGPT .
    Dan Ives of Wedbush Securities said in a client note on Tuesday, referring to Microsoft’s chief executive: “This OpenAI investment/strategic partnership which is likely in the $10 billion range is a game changer in our opinion for Nadella & Co .”
This move by Microsoft into the AI market has clearly paid off  as their investment in OpenAI has proven to be a wise decision . The recent growth in their share price can be attributed to the launch of ChatGPT , which has received positive reviews and highlights the importance of AI in our future.

However, the issue with Google Bard’s misleading response highlights the potential dangers of AI-generated answers and the importance of thoroughly testing these systems before they are launched. The company has responded by launching a Trusted Tester program, which will combine external feedback with their own internal testing to ensure that Bard ’s responses meet high standards for quality, safety and accuracy.

Overall, it is clear that AI technology is rapidly advancing and changing the world, but it’s important for companies to take caution and implement proper testing procedures before unleashing these systems on the public. While AI may offer new and exciting possibilities it’s crucial to remember the potential risks and ensure that these systems are reliable and trustworthy .

To start, ensure that XAMPP is running and all the necessary services (Apache, PHP, and MariaDB) are active. You can check this in the XAMPP control panel.

Next, locate the htdocs or www directory within the XAMPP folder on your PC. This is where you will save all your PHP files and folders. To test your PHP installation, create a file named "test.php" within this directory.


<?php

echo "Hello World";

 ?>
Save the file and access it through your web browser. If everything is set up correctly, you should see the message "Hello World!" displayed in your browser.
  "In order to run a PHP file on your local system, you will need to access it through a web browser. This can be achieved by using the following URL format: localhost://[filename]. Replace [filename] with the name of your PHP file, including the .php extension. For example, if your file is named test.php, the URL to access it in your browser would be localhost://test.php. Ensure that your web server (such as XAMPP) is running and configured correctly before attempting to access the PHP file in your browser."

How to Actually Write Good Quality Content (Short Article)
2020-02-16T01:31:00.000+05:30



Mohammad Shakeel (CoolMitra)





Do you know something which you can explain with great examples, facts, research and observation?

Have something to write about?




Yes?




Then here we go, now you can earn money from it.




But, if you only want to get readers because you are already reading this article in iPhone 11 while seating in luxurious home/car then may be you would want to start your writing online article to get readers for your written stuff (not for money).




Then it's more better option for you to start a blog, if you want to write for readers but not for dollars.




Of course making money is also important but keep it secondary. The reason why I'm saying this is because I tried to start many blogs with dreaming lots of money, but failed to work continuously.




But, when I started writing from my heart and for readers, then I started touching million's of hearts.




Hy, you are reading words of Mohammad Shakeel, who is founder of mshakeel.com (Online Learning Platform), creator of CoolMitra (India's one of the best Motivational YouTube Channel) and India's most youngest Motivational speaker.




The reason why you need to read this is because more than 1.6M people clicked on my subscribe button of my YouTube channel. Why those people subscribed to me? because I write from my heart that's why I touched those hearts.




After getting 80Million views on my 3 years old CoolMitra YouTube Channel here I'm going to share one thing with all of you guys.




Let's start it.




Write When You Feel, Not When You Need


"A Writer is a World Trapped in a Person." - Victor Hugo


Obviously, at starting point you need to write without feel but later after getting great writing skill, you need to write with feel.




For example, if you hate to write about financial topics, but you are writing about it because you want to gain more articles on your blogs or someone told you this topic/niche makes you more money, then nobody will return to to your blog after reading your financial blogs.




Why?




Because when you don't write with feel, readers will understand that the article they are reading is garbage not value adding content.




I have to make one or sometimes 2 videos for a week, but when I don't feel like writing, I don't.




Because when I will still force myself to write, I will lose my subscribers attentions on my next content.




Key point?




Write when you feel not when you need to write.






Start Learn PHP/MYSQL : What Is MySQL ? Why MySQL ?
2016-05-08T16:40:00.003+05:30







MySQL is the most popular database system used with PHP. MySQL is an open-source relational database management system (RDBMS). In July 2013, it was the world's second most widely used RDBMS, and the most widely used open-source client–server model RDBMS It is named after Michael Widenius' (who is a co-founder of MySQL) daughter, My, while "SQL" stands as the abbreviation for Structured Query Language. The MySQL development project has made its source code available under the terms of the GNU General Public License, as well as under a variety of proprietary agreements. MySQL was owned and sponsored by a single for-profit firm, the Swedish company MySQL AB, now owned by Oracle Corporation. For proprietary use, several paid editions are available, and offer additional functionality.



What Is MySql:



MySQL is a database system used on the web

MySQL is a database system that runs on a server

MySQL is ideal for both small and large applications

MySQL is very fast, reliable, and easy to use

MySQL uses standard SQL

MySQL compiles on a number of platforms

MySQL is free to download and use

MySQL is developed, distributed, and supported by Oracle Corporation

PHP combined with MySQL are cross-platform (you can develop in Windows and serve on a Unix platform)

Definition And Features

MySQL is a relational database system. MySQL is faster, more reliable, and Free , better than any other database system (including commercial systems such as Oracle and DB2).We can safely say that there is a large bandwidth of opinion.

There is an ever increasing number of MySQL users, and majority of them are quite satisfied with MySQL.

Its also that MySQL still lacks a number of features that are taken for granted with other database systems. If you require such features, then MySQL is not the database system for you.

Features of MySQL

The following list shows the most important properties of MySQL. This section is directed to the reader who already has some knowledge of relational databases. We will use some terminology from the relational database world without defining our terms exactly. On the other hand, the explanations should make it possible for database novices to understand to some extent what we are talking about.

Relational Database System: Like almost all other database systems on the market, MySQL is a relational database system.

Client/Server Architecture: MySQL is a client/server system. There is a database server (MySQL) and arbitrarily many clients (application programs), which communicate with the server; that is, they query data, save changes, etc. The clients can run on the same computer as the server or on another computer (communication via a local network or the Internet)

Almost all of the familiar large database systems (Oracle, Microsoft SQL Server, etc.) are client/server systems. These are in contrast to the file-server systems, which include Microsoft Access, dBase and FoxPro. The decisive drawback to file-server systems is that when run over a network, they become extremely inefficient as the number of users grows.

Why MySQL?

Many of the world's largest and fastest-growing organizations including Facebook, Google, Adobe, Alcatel Lucent and Zappos rely on MySQL to save time and money powering their high-volume Web sites, business-critical systems and packaged software.

Type Of Query Example:

Create Statement:Use To Create Database and Tables






CREATE DATABASE dbname;
For Tables:




CREATE TABLE table_name
(
column_name1 data_type(size),
column_name2 data_type(size),
column_name3 data_type(size),
....
);
Alter Statement:is used to add, delete, or modify columns in an existing table

To add a column in a table, use the following syntax:




ALTER TABLE table_name
ADD column_name datatype
To delete a column in a table:




ALTER TABLE table_name
DROP COLUMN column_name
To change the data type of a column in a table:




ALTER TABLE table_name
ALTER COLUMN column_name datatype
Insert Statement:is used to add new records to a MySQL table




INSERT INTO table_name (column1, column2, column3,...)
VALUES (value1, value2, value3,...)
Update Statement:is used to update existing records in a table




UPDATE table_name
SET column1=value, column2=value2,...
WHERE some_column=some_value 
Delete statement: is used to delete records from a table




DELETE FROM table_name
WHERE some_column = some_value

Select Statement:Its Use Display all the data From Table




SELECT * FROM table_name





Start Learn PHP/MYSQL: What is PHP ? How to Learn PHP Easily ?
2016-04-29T00:02:00.003+05:30

It has been quite some time since I started working as a PHP developer , and I've been contemplating the idea of sharing my knowledge of PHP with readers. In this post, I aim to provide an overview of PHP for beginners.

Definition and Full Form:
To begin with, PHP is a server-side scripting language that was first introduced by Rasmus Lerdorf in 1994. The term PHP is an acronym that stands for Personal Home Page, but it is now more commonly referred to as PHP: Hypertext Preprocessor.
What is server-side scripting language?

Server-side scripting language execute (run) on the server. server-side environment that runs a scripting language is a web server. A user 's request is fulfilled by running a script directly on the web server to generate dynamic HTML pages. This HTML is then sent to the client browser. It is usually used to provide interactive web sites that interface to databases or other data stores on the server.



As a server-side scripting language, PHP is primarily used for building dynamic web applications that can run on various web servers, such as Apache and Nginx. With PHP, developers can create web pages that can interact with databases, process user input, and generate dynamic content.

For beginners who are just starting to learn PHP, it is essential to understand the basics of the language, such as its syntax and structure. PHP code is executed on the server, and the output is sent to the user's browser in the form of HTML. To execute PHP code , it must be written within special tags that start with "".

One of the significant benefits of PHP is its compatibility with various platforms and operating systems, including Windows, Linux, and macOS. Additionally, PHP has a vast community of developers who have created numerous frameworks, libraries, and tools to make web development faster and more efficient.
What You Mean By Hypertext Preprocessor ?

Hypertext Preprocessor (It is a recursive acronym, if you can understand what that means.) PHP is an HTML-embedded Web scripting language. This means PHP code can be inserted into the HTML of a Web page. When a PHP page is accessed, the PHP code is read or "parsed" by the server the page resides on. The output from the PHP functions on the page are typically returned as HTML code, which can be read by the browser. Because the PHP code is transformed into HTML before the page is loaded, users cannot view the PHP code on a page. This make PHP pages secure enough to access databases and other secure information.

PHP-related and supporting projects, such as PEAR, PECL, and documentation, and an underlying network infrastructure of well over one-hundred individual web servers on six of the seven continents of the world.
