HOW to Divide the time

2011-10-06T17:09:00.001+05:30

Hi friends today i want to display the logic behind the , time division in your programming as well as daily routine work or to crack the math questions also..

Lets take an example :

Suppose I have 5 hours and 30 minutes (5h30m)

Then the step I follow are:

First divide the hours by 2 . like 5/2 we got 2 as dividend and 1 as reminder.

Now convert this reminder to minutes by multiplies it to 60.

After that add this 60 to the 30(already given minutes).

total is 90 (minutes you have).

then divide the Ninety by 2 we got 45.

So at last, half of the given time is 2 hour 45 (2h 45m)

Basically we have to make the conversion like

hours:minutes:seconds format.

The same logic work for Minutes and second (mm::ss) format

Hope you got the point.....

cake php

2011-08-11T13:54:00.010+05:30

Before read this i think you have some programming knowledge and client server architecture.
What is Cake PHP:

a quick list of features you’ll enjoy when using CakePHP:
Active, friendly community
Flexible licensing
Compatible with versions 4 and 5 of PHP
Integrated CRUD for database interaction
Application scaffolding
Code generation
MVC architecture
Request dispatcher with clean, custom URLs and routes
Built-in validation
Fast and flexible templating (PHP syntax, with helpers)
View Helpers for AJAX, JavaScript, HTML Forms and more
Email, Cookie, Security, Session, and Request Handling Components
Flexible ACL
Data Sanitization
Flexible Caching
Localization
Works from any web site directory, with little to no Apache configuration involved

Requriment for cake php:

Requirements
- HTTP Server. For example: Apache. mod_rewrite is preferred, but by no means required.
- PHP 4.3.2 or greater. Yes, CakePHP works great on PHP 4 and 5.
CakePHP supports a variety of database storage engines:
- MySQL (4 or greater)
- PostgreSQL
- Microsoft SQL Server
- Oracle
- SQLite

It is a MVC based php framework for rapid application development.

Used to build a rapidly develop robust web applications, without any loss to flexibility.

Now what is MVC in very easy and static way i explain in 6 step:

See the picture above it helps you a lot:

step 1 : User send a request for page.
step 2 : Request goes to server's controller.
step 3 : Controller find the specific page in model(also called a database table , rss feed or any other file) .
step 4 : If found come back to controller and after that controller.
step 5 : Then controller goes to the view, it is the view who represent the data in the form of html or pdf or other way.
step 6 : At last it is the view that transfer to the client back.

This is all over MVC hope you got it...
here the file structure of cake php :

the Root folder contain:

/app
/cake
/plugins
/vendors
.htaccess
index.php
README

The app folder will be where you work your Programming Code files: it’s where your application’s files will be placed.
The cake folder contained very useful predefined data files. make sure that you never edit files in this folder. This is the core of Cake .
Finally, the vendors folder is where you’ll place third-party PHP libraries you need to use with your CakePHP applications.

The App Folder

CakePHP’s app folder is where you will do most of your application development. Let’s look a little closer at the folders inside of app.

config :	Holds the (few) configuration files CakePHP uses. Database connection details, bootstrapping, core configuration files and more should be stored here.
controllers	:Contains your application’s controllers and their components.
libs:	Contains 1st party libraries that do not come from 3rd parties or external vendors. This allows you to separate your organization's internal libraries from vendor libraries.
locale:	Stores string files for internationalization.
models:	Contains your application’s models, behaviors, and datasources.
plugins:	Contains plugin package.
tmp:	This is where CakePHP stores temporary data. The actual data it stores depends on how you have CakePHP configured, but this folder is usually used to store model descriptions, logs, and sometimes session information. Make sure that this folder exists and that it is writable, otherwise the performance of your application will be severely impacted. In debug mode, CakePHP will warn you if it is not the case.
vendors:	Any third-party classes or libraries should be placed here. Doing so makes them easy to access using the App::import('vendor', 'name') function. Keen observers will note that this seems redundant, as there is also a vendors folder at the top level of our directory structure. We'll get into the differences between the two when we discuss managing multiple applications and more complex system setups.
views:	Presentational files are placed here: elements, error pages, helpers, layouts, and view files.
webroot:	In a production setup, this folder should serve as the document root for your application. Folders here also serve as holding places for CSS stylesheets, images, and JavaScript files.

Another important point is CakePhp Convension:

CakePHP Conventions:

It will take a time to learn CakePHP’s conventions.
But this will helps you save time in the long run.
By the following convention you able to do:

the maintenance nightmare of tracking config files.
Convention also makes for a very uniform system development.
Allowing other developers to jump in and help more easily.

File and Classname Conventions:

In general, filenames are underscored while classnames are CamelCased. So if you have a class MyNiftyClass, then in Cake, the file should be named my_nifty_class.php. Below are examples of how to name the file for each of the different types of classes you would typically use in a CakePHP application:

The Controller class KissesAndLovesController would be found in a file named kisses_and_loves_controller.php (notice _controller in the filename)
The Component class MyFutureComponent would be found in a file named my_future.php
The Model class OptionValue would be found in a file named option_value.php
The Behavior class MyNewBehavior would be found in a file named my_new.php
The View class SuperSimpleView would be found in a file named super_simple.php
The Helper class BestEverHelper would be found in a file named best_ever.php

Each file would be located in or under (can be in a subfolder) the appropriate folder in your app folder.

--------------------------------------------------------------------------------

Model and Database Conventions:

Model classnames are singular and CamelCased. Person, BigPerson, and ReallyBigPerson are all examples of conventional model names.

Table names corresponding to CakePHP models are plural and underscored.
The underlying tables for the above mentioned models would be people, big_people, and really_big_people, respectively.
Field names with two or more words are underscored like, first_name.

Controller Conventions:

Controller classnames are plural, CamelCased, and end in `Controller`. `PeopleController` and `LatestArticlesController` are both examples of conventional controller names.

C.T.M:

The first method you write for a controller might be the index() method.
When a request specifies a controller but not an action, the default CakePHP behavior is to execute the index() method of that controller.
For example, a request for http://www.example.com/apples/ maps to a call on the index() method of the ApplesController, whereas http://www.example.com/apples/view/ maps to a call on the view() method of the ApplesController.

URL Considerations for Controller Names:

As you've just seen, single word controllers map easily to a simple lower case URL path. For example, ApplesController (which would be defined in the file name 'apples_controller.php') is accessed from http://example.com/apples.

i keep updating this : stay tuned.... thanks ..

View Conventions:

View template files are named after the controller functions they display, in an underscored form.
The getReady() function of the PeopleController class will look for a view template in /app/views/people/get_ready.ctp.
The basic pattern is /app/views/controller/underscored_function_name.ctp.

Here’s a final example that ties the conventions

Database table: "people"
Model class: "Person", found at /app/models/person.php
Controller class: "PeopleController", found at /app/controllers/people_controller.php
View tem
plate, found at /app/views/people/index.ctp

-------------------------------------------------------------------
Let us start some delelopment:
The next big thing you have to done is:

Creating the Blog Database:

if you haven't already done this, create an empty database for use in this tutorial, with a name asn you wish.

create table name posts
1. /* First, create our posts table: */
2. CREATE TABLE posts (
3. id INT AUTO_INCREMENT PRIMARY KEY,
4. title VARCHAR(50),
5. body TEXT,
6. created DATETIME DEFAULT NULL,
7. modified DATETIME DEFAULT NULL
8. );
9. /* Then insert some posts data for testing: */

After that:

Controller in brief:-

if you were building a site for an online examsystem, you might have a OnlineexamController .
In CakePHP, controllers are named after the model they handle, in plural form.
So the The OnlineExam model is handled by the OnlineexamController and so on.
Imp Point remember:

Your application's controllers are classes that extend the CakePHP AppController class, which in turn extends a core Controller class, which are part of the CakePHP library.
The AppController class can be defined in /app/app_controller.php and it should contain methods that are shared between all of your application’s controllers.

Controllers can include any number of methods called as actions.
Actions are controller methods used to display views. An action is a single method of a controller.

<?    class OnlinexamController extends AppController {
        function view($id)     {
            //action logic goes here..
        }

        function share($student_id, $stuname_id) {
            //action logic goes here..
        }

        function search($query) {
            //action logic goes here..
        }
    }

    ?>

Format a number in php

2011-08-10T17:39:00.004+05:30

for this we have a function called : number_fomat();

Syntax is:

< ?php

$myno=123456;

$myno_after_format=number_format($myno);

echo $myno_after_format;

output is:123,456

also another way:

$myno=1234.56;

# this will show only one decimal digit.

$myno_after_format=number_format($myno,1);

echo $myno_after_format;

output is:

Php Array types

2011-08-02T15:48:00.001+05:30

Array is a datatype in php...

It is mostly used to store multiple item under a single variable name.

Types of array in PHP:

1.Numeric or Index array.
2.Associative array.
3.Multi-dimensional array.

1. Numeric array:

syntax to create this:

php code begin here

/*
#Write a program to Numeric array in PHP
#comment: make a array variable name $var
#Author : amit sharma
*/

$var = array (value1,value2,value3...);

#in detail

$var = array(10,20,30,40,50,60);

now in above line we create a array name $var in php that store 6 values 10,20,30,40,50 and 60 .

PHP difference between single and double quotes

2011-07-25T18:54:00.002+05:30

1. Single quote treat all variable as string. while double quotes treat variable and string diferent.
2. 'Single quote ' are effective with . (concatenation operator), while less need of . operator by using "double quote"

example:

Double Quote

$my_var_name=120;

echo "the value is $_my_var_name";

output is:

the value is 120

----------------------------------------------------------

Single Quote

$my_var_name=120;

echo "the value is $_my_var_name";

output is:

the value is $_my_var_name

So i think ,the difference clear to you.

New OOPs Concept with PHP5.

Here i am begin small tutorial for beginner as well as Professional..

Class:- It is an real world entity, like Person, Car, Employee etc

it contain properties also call variable and functions or Methods.

Object:- it is the instance of class. it like a variable , that is capable of using all class member variable as well as class member function.

Constructor: it is the important part of Class,behave like a function. It is a class function that execute automatically when we declare the object of that class.

their is no need to execute constructor by calling method. example

class className

{

//in php5

function __construct()
{// this is the constructor , here we mention such type of statements that execute automatically when the object is created.
}

}// end of class

ACCESS MODIFIERS :
the access modifiers are those who will specify the Scope of variable as well as functions...
here the name of some are as:
