Multilingual html pages using basic html, javascript and jquery

2011-09-24T01:59:00.000-07:00

Here I am helping how to set the Multilingual html pages using html, javascript and jquery without using programming languages like (php, .net, java).

The main reason for using this code is

-very easy to set up on your pages.

-without using any programming languages like php, .net or java we can change the language on our web pages.

-Its not required session to store the lang in our pages .

-No need to refresh the page.

-On refreshing the pages previously selected lang will sustain in pages.

-Very easy to modify as per your requirement.

Please follow these steps to set up this code in your web pages.

Step1: create html page and copy paste the following code .

<html >
     <head>
     <meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
     <title>Language</title>
     <script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.6.4/jquery.min.js"></script>
     <script type="text/javascript">
     //to get the lang selected last time from the cookie
           function getCookie(c_name)
           {
               var i,x,y,RKcookies=document.cookie.split(";");
              for (i=0;i<RKcookies.length;i++)
              {
                     x=RKcookies[i].substr(0,RKcookies[i].indexOf("="));
                     y=RKcookies[i].substr(RKcookies[i].indexOf("=")+1);
                     x=x.replace(/^\s+|\s+$/g,"");
                     if (x==c_name)
                    {
                        return unescape(y);
                    }
              }
        }
        //setting up cookie for selected lang 
	function setCookie(c_name,value,exdays)
	{
	         var exdate=new Date();
	        exdate.setDate(exdate.getDate() + exdays);
	        var c_value=escape(value) + ((exdays==null) ? "" : "; expires="+exdate.toUTCString());
	       document.cookie=c_name + "=" + c_value;
	}
	//this function calls by default by body on load 
       //this function checks if any lang is there in cookie if not select default lang as en  
       function checkCookie()
       {	
	     var lang=getCookie("lang");
             if (lang!=null && lang!="")
            {
	             changeLang(lang);//chnaging the body content as per lang   
            }
           else 
           {
  	             // here 1 is the expire day.  cookie vl expire  after that 
	           setCookie("lang",'en',1);//setting cookie with the default vlang as en(english)
	            changeLang(lang);		//chnaging the body content as per lang   
           }
       }
           //switch case checking to chnage the lang in body content
          function changeLang(lang)
         {
	         switch(lang)
	         {
	           case 'en': $("#divcontent").html("Multilingual html pages using html and jquery"); break;
	           case 'fn':	$("#divcontent").html("Multilingue des pages HTML en utilisant le HTML et jQuery");break;
	           case 'ch':$("#divcontent").html("多种语言的HTML页面中使用HTML和jQuery"); break;
	        }
         }

        //changing  the lang on selecting form the li list 	
        function changelangDisplay(lang)
       {
	      if (lang!=null && lang!="")
              {
    	             setCookie("lang",lang,1);		
		     changeLang(lang);			
               }
        } 
      </script>
       </head>

         <body onload="checkCookie();" >
                 Please select the language here.....
                <li onclick="changelangDisplay('en');">English</li>
                <li onclick="changelangDisplay('fn');">Française</li>
               <li onclick="changelangDisplay('ch');">中文</li>

            <br />
             <br />
            <div id="divcontent">Multilingual html pages using html and jquery</div>

        </body>
</html>
Step 2:  jquery library file is being linked with Google if want u can change it to your downloaded.
            <script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.6.4/jquery.min.js"></script>


Step 3: in body onload function
	“checkCookie()” is called where you can change default lang value ” en” to lang u want  
	and expire days for your cookie “1” can also change .

step 4:function “changeLang(lang)”here you can define the languages content for your web pages as per selected switch case and you can add cases you wanted as per the  list showing in body content.

setp 5: function “changelangDisplay(lang)” this function will be called on selecting languages from the list and don’t worry this function will also set the lang cookies. 

Don’t you find it easy after setting up ……… For any fix you can contact me

How to connect SQLite in PHP

2010-06-25T02:47:00.000-07:00

Introduction

The PHP Data Objects (PDO) extension defines a lightweight, consistent interface for accessing databases in PHP. Each database driver that implements the PDO interface can expose database-specific features as regular extension functions.

This allows developers to create code which is portable across many databases and platforms. and this Focus on data abstraction rather than database abstraction

LIst of Databases supported by PDO

* MS SQL Server (PDO)

* Firebird/Interbase (PDO)

* IBM (PDO)

* Informix (PDO)

* MySQL (PDO)

* Oracle (PDO)

* ODBC and DB2 (PDO)

* PostgreSQL (PDO)

* SQLite (PDO)

* 4D (PDO)

Here I am giving the setps to connect SQLite database in php before you start setting up u need to enable the extension=php_pdo_sqlite.dll and
extension=php_sqlite.dll (in case php 5 >) or php_pdo.dll then restart your apache server

Step1 : connect to the SQLite databse using PDO. By using PDO the database creation becomes even easier. Simply specify the path to the database file and it will be loaded. If the database file does not exist, PDO will attempt to create it.

<?php
try {
         // connect to SQLite from PDO database
         $dbh = new PDO("sqlite:/path/to/database.db");

}
catch(PDOException $e)
{
         echo $e->getMessage();//this getMessage throws an exception if any

}
?>

Step2 :now run the query by using the database object created
$result = $dbh->query($query);
while($row = $result->fetch())
{
         print("$row["fieldname"]");
}

Sample code
Here i am Creating database name "database" and the table TestTable.

<?php
try {

         // connect to SQLite from PDO database

         $dbh = new PDO("sqlite:database.db");

}
catch(PDOException $e)

{
          echo $e->getMessage();
}
    $query = 'CREATE TABLE TestTable ' .
     '(Title TEXT, Name TEXT, Year INTEGER)';

    $result = $dbh->query($query);

if(!$dbh->query($query))
{
       echo "table not created ";

}

$query =
             'INSERT INTO TestTable (Title, Name, Year) ' .
            'VALUES ("Mr", "Rakesh", 2010); ' .

              'INSERT INTO TestTable (Title, Name, Year) ' .
             'VALUES ("Mr", "Ram", 2008)' ;
if(!$dbh->query($query))
{
            echo "row not inserted ";
}
$query = "SELECT * FROM TestTable";

if($result = $dbh->query($query))

{

      while($row = $result->fetch())
   {
             print("Title: {$row['Title']} " .
             "Name: {$row['Name']}".
             "Year: {$row['Year']}");
      }
}
else
{
          echo "not selected ";
}

How to fix the FlexiGrid Height and Width dynamically based on the screen resolution

2010-06-05T03:51:00.000-07:00

FelxiGris is Lightweight but rich data grid with resizable columns and a scrolling data to match the headers, plus an ability to connect to an xml based data source using Ajax to load the content
To Set up the flexigrid click here

Once your flexigrid setup is over you may face problem of fixing the height and width of the grid which is defined as constant value in setup . instead of setting it as constant value you can make it as dynamic
Here I am giving the steps to make it as dynamic
Step 1.
If you flexigrid component is calling inside the div tag or table tag follow the height and width as in terms of percentage
Step 2.
Sample table structure where u can place the flexigrid table
<table > border=”0” height=”100%” width=”100%”>
<tr height=”22”><td height=”20”>header if any</td></tr>
<tr height=”100%”><td height=”100%”> <!—100% to take rest of space -->
<div id=”flexigridDiv” ><table id="flex1"></table></div>
</td>
</tr>
</table>
Step3.
Then inside the flexigrid calling function set the height as
$("#flex1").flexigrid({
url: url,
dataType: 'json',
colModel : [
{display: name, name : 'idx', width : 40, sortable : true, align: 'center'},
{display: 'age', name : 'age', width : 100, sortable : true, align: 'left'},
{display: 'Description', name : 'description', width : 120, sortable : true, align: 'left'}
],
sortname: "idx",
sortorder: "desc",
usepager: true,
useRp: true,
rp: 20,
showTableToggleBtn: true,
onSubmit: addFormData,
height: $(“ #flexigridDiv”).innerHeight(); //this takes the height of the 2nd tr dynamically
});

         //Click the button event!
        $("#openpopup").click(function(){
        //centering with css
        aligncenter();
       //load popup
       loadPopup();
       });
       //CLOSING POPUP
      //Click the x event...
      $("#Closepopup").click(function(){
          disablePopup();
     });
     //Click out event..
        $("#backgroundPopup").click(function(){

     });
     //Press Escape event...
       $(document).keypress(function(e){
           if(e.keyCode==27 && popupStatus==1){
              disablePopup();
           }
      });
})
//0 means disabled; 1 means enabled;
var popupmain = 0;
//loading popup with jquery component
function loadPopup(){
       //loads popup only if it is disabled
       if(popupmain==0){
            $("#backgroundPopup").css({
                "opacity": "0.7"
            });
       $("#backgroundPopup").fadeIn("slow");//to fade in the content slowly
       $("#maincontent").fadeIn("slow");//main pop up content opens slowly
       popupmain = 1;//changing once the popup is opened fro the next time popup content
     }
}
//disabling popup with jQuery magic!
function disablePopup(){
         //disables popup only if it is enabled
        if(popupmain==1){
                 $("#backgroundPopup").fadeOut("slow");
                $("#maincontent").fadeOut("slow");
               popupmain = 0;
          }

Mysql-PHP in JAVA using quercus resin server in windows

2009-12-08T03:57:00.002-08:00

Mysql connection with the quercus resin server from java module

In the previous post you can see the installation of the resin server with the hello world example now in this post you can see the mysql connection with the java module in quercus resin server

Here I want to show that basic php-mysql application can be make it run with the java module using resin server where you can write db connection in java and make use of connection in php pages

List of API or jar files required to execute this .

1.mysql-connector-java-5.1.5-bin.jar (from mysql’s download page) (http://www.mysql.com/products/connector/)
2. quercus.jar (in the quercus zip from caucho)
3. resin-util.jar (in the quercus zip from caucho)
4. script-10.jar (in the quercus zip from caucho)
Put all this jar files in lib folder

Follow the steps to setup the mysql-php-java module

Step 1.
Inside \resin-pro-3.1.9\webapps\ROOT\WEB-INF folder create web.xml with the following code

servlet-class="com.caucho.quercus.servlet.QuercusServlet"/>

jdbc:mysql://localhost:3306/test
root

Step2.
inside \resin-pro-3.1.9\webapps\ROOT\WEB-INF\classes\example create java class file with the

DBconnect .java

package example;
import java.io.PrintWriter;
import java.sql.Connection;
import java.sql.Statement;
import java.sql.ResultSet;
import java.sql.SQLException;
import javax.sql.DataSource;
import javax.naming.InitialContext;
import javax.naming.Context;
import javax.naming.NamingException;
import java.io.*;
import java.sql.*;
import java.util.*;
import javax.servlet.*;
import com.caucho.quercus.module.AbstractQuercusModule;
public class DBconnect extends AbstractQuercusModule{
/**
* The DataSource for the table.
*/
private DataSource _ds = null;
/**
* Sets the data source.
*/
public void setDataSource(DataSource ds)
{
_ds = ds;
}
/**
* Initializes the reference to the CourseBean home interface.
*/
public String test_fun()
{
return "Hello raki ";
}
public String conn_db()
{
Connection conn = null;
Statement stmt = null;
ResultSet rs = null;
String rtn_str=" ";

try
{
conn=DriverManager.getConnection("jdbc:mysql://localhost/testdb?" + "user=root"); //change testdb to your database name
stmt = conn.createStatement();
//rtn_str+="\n middle \n";
if (stmt.execute("SELECT * FROM table")) {
rs = stmt.getResultSet();
while(rs.next())
{
String filed1 = rs.getString("filed1");//change filed1 to your table column
String filed2 = rs.getString("filed2");//change filed2 to your table column
rtn_str+= " filed1:-"+ filed1 + " filed2:- " + filed2 +"
";
//rtn_str+=" \n"+rs.getInt(1)+"\n";
}
}

}
catch(Exception e)
{
}

//rtn_str+="<\pre>";
return rtn_str;
}

}

Step3.
inside \resin-pro-3.1.9\webapps\ROOT\WEB-INF\classes\META-INF\services create the following file with name “com.caucho.quercus.QuercusModule” put the content

example.DBconnect

step4.
Now inside \resin-pro-3.1.9\webapps\ROOT create the php page which calls the java module with name php_mysql_java.php

echo "your module data comes here “."
";
echo conn_db ().”
";

?>

Step 5.
Now run the hello_world.php from the URL as
http://localhost:8080/ php_mysql_java.php

You should see “your module data comes here
The data base values should comes here ”

PHP in JAVA using quercus resin server in windows

2009-12-08T03:57:00.001-08:00

Quercus is Caucho Technology's fast, open-source, 100% Java implementation of the PHP language

Quercus is written for Resin, a Java application server.

If your using resin server then you can able to call java module from the php page . but here I am showing running of php file with the tomcat server using java compiler
The interesting thing is you can import java libraries or module from php page.
Follow the setps to install the quercus (resin server)

Step1.
Download the resin server installation package from the this page(http://www.caucho.com/download/)

Step2.
Unzip downloaded file and put it inside the your c drive

Step3.
dont forgot to install JDk(1.5 or >) and set the environment path for the same

Step4.
when you open resin main folder(\resin-pro-3.1.9) you can see http file click on it and that will start your resin server
NOTE:-in case if you’re not able to run the resin server
Step1.you can see the setup file inside the main resin folder run that folder it will ask you some configuration

Step2.click on the apache server option and give the root path to the apache where you have installed apache so that it can able to access the apache http.conf file form there.

Step3.then press apply and then start http file it should start your resin server now

Step4. In worst case you can able to start the resin sever from the command prompt eit the following command . change the path in to your resin main folder and then run this command” cd:\resin>java –jar lib/resin.jar start” .

Step5.now open browser and type http://localhost:8080/ you should see the default page of the resin server if that comes your installation is correct. then proceed further

Step 6. Inside \resin-pro-3.1.9\webapps\ROOT\WEB-INF folder create web.xml with the following code

servlet-class="com.caucho.quercus.servlet.QuercusServlet"/>

Step7.
inside \resin-pro-3.1.9\webapps\ROOT\WEB-INF\classes\example create java class file with the

HelloWorld .java

package example;

import com.caucho.quercus.module.AbstractQuercusModule;

public class HelloWorld extends AbstractQuercusModule {
/*
** Notice the careful use of the naming
** convention hello_test. This is done
** in order to prevent name collisions
** among different libraries.
*/
public String hello_test(String name)
{
return "Hello, " + name;
}
}

Step8.
inside \resin-pro-3.1.9\webapps\ROOT\WEB-INF\classes\META-INF\services create the following file with name “com.caucho.quercus.QuercusModule” put the content

example.Helloworld

step9.
Now inside \resin-pro-3.1.9\webapps\ROOT create the php page which calls the java module with name hello_world.php

echo "your module data comes here “."
";
echo hello_test("World")."
";

?>

Step 10.
Now run the hello_world.php from the URL as
http://localhost:8080/hello_world.php

You should see “your module data comes here
hello world”

Virtual Host concept in apache configuration and proxy Apache server

2009-11-05T04:15:00.000-08:00

The term Virtual Host refers to the practice hosting more than one website in server on one machine. For example in single sever they can maintain multiple website with different host name as www.example1.com and www.example2.com, without requiring the user to know any extra path information.
How to configure virtual host in different scenarios in your http.config file is defined here

++The common basic virtual host setting
# Virtual hosts
NameVirtualHost 192.1.1.1:80

serverName localhost
Document localhost

In the above through IP address and the port number you can set the sever name in localhost and the
Root Document files path to select root path of the site

++Get information about the requests being processed by the server and the
configuration of the server.
Required modules: 1.mod_status (for the server-status handler),
2.mod_info (for the server-info handler)

SetHandler server-status
Order deny,allow
Deny from all
Allow from .localhost

++ Settings for hosting different languages.

Required modules: mod_mime, mod_negotiation
DefaultLanguage and AddLanguage allows you to specify the language of a document. You can then use content negotiation to give a browser a file in a language the user can understand.

DefaultLanguage nl
AddLanguage ca .ca
AddLanguage cs .cz .cs
AddLanguage da .dk
AddLanguage de .de
AddLanguage el .el
AddLanguage en .en
AddLanguage eo .eo

++If you want to maintain multiple domains/hostnames on your machine

Most configurations use only name-based virtual hosts so the server doesn't need to worry about IP addresses. This is indicated by the asterisks in the directives below.

ServerAdmin webmaster@dummy-host.localhost
DocumentRoot /www/docs/dummy-host.localhost
ServerName dummy-host.localhost
ServerAlias www.dummy-host.localhost
ErrorLog logs/dummy-host.localhost-error_log
CustomLog logs/dummy-host.localhost-access_log common

ServerAdmin webmaster@dummy-host2.localhost
DocumentRoot /www/docs/dummy-host2.localhost
ServerName dummy-host2.localhost
ErrorLog logs/dummy-host2.localhost-error_log
CustomLog logs/dummy-host2.localhost-access_log common

Proxy Apcahe server

An ordinary forward proxy is an intermediate server that sits between the client and the origin server. In order to get content from the origin server, the client sends a request to the proxy naming the origin server as the target and the proxy then requests the content from the origin server and returns it to the client. The client must be specially configured to use the forward proxy to access other sites.

Required modules:proxy_module , proxy_http_module , proxy_balancer_module

ServerName dummy-host.localhost
ErrorLog logs/dummy-host.localhost-error_log

ProxyRequests Off
proxyPreserveHost on

Order deny,allow
Allow from all

ProxyPass / dummy-host
ProxyPassReverse / dummy-host

Order deny,allow
Allow from all

Installing PHPUNIT2 on Windows system

2009-10-29T05:03:00.001-07:00

The following post gives u a detail information about installation of PHPUNIT2 into your wamp server on windows system

Step1. Check your wamp has installed properly on windows system. If it is then open wamp folder and go to the php folder and you should find go-pear.bat file

Step2. open command prompt and go to php directory in wamp

C:\> cd wamp\php

If your wamp structure is different then check for following path

C:\>cd wamp\php\php5.5

But here I am following the wamp\php path for installation. if yours is different than please follow as in your wamp instead of “wamp\php”

Step3. Run go-pear.bat batch file from this place for complete installation of pear into your wamp php server

C:\cd wamp\php>go-pear.bat

Here it will ask you for some conformation if you don’t know then go with the default selection like [system | local]system:”select system here”

Complete the process like this with all default selection

Step4. once the installation is completed run PEAR_ENV.reg file from this place so that environment variable can be created to the for the user running wamp server. Then only your able to access pear files anywhere in the document root folder

NOTE:if your unable to create environment variable then manually you can create with following steps

Click on system properties->select advanced->Environment variables

Here you can add directory path variable “ c:\wamp\php”

Step5. Once your pear setup is over you must register your phpunit channel with the pear registry

C:\wamp\php>pear channel-discover pear.phpunit.de

Step6. Once the register is over now your able to install all supporting packages from the phpunit channel

C:\wamp\php>pear install pear/phpunit2

Then it may ask you to install all supporting packages for phpuint like

C:\wamp\php>pear install pear/benchmark

C:\wamp\php>pear install pear/console_Getopt

Step7. Now you will find phpunit folder under php\pear folder where all subfolder with all utilities will be there now your phpunit as configured and its ready to use in your project

Creating recursive folders in linux server through php script

2009-10-08T04:39:00.000-07:00

Creating recursive folders in linux server through php script

while creating directory inside your root folder or in any folder through php script you should take care of the following steps.

which may gives you problem by not creating folder under any root folder

In some linux server if your warrings are off then it won’t give warring msg if any following error raise

this type of problem you may get when you’re trying to create folder recursively

Here I am giving the list of problem

1)permission

2)owner permission

3)group permission

4)most important safe mode ON in linux server

– If your having problem of not creating folder under any root folder or under any other folder (permission problem)

-pls check the root permission for the folder under which your trying to create dir through php

Or through php itself you can able to change the permission for the folder like this

$chmod_value = chmod(“/root/folder/”,0755);

-don’t giv full permission for the source folder where your trying to create max 755 is enough.

-if your not able to create due to owner permission then

-pls check under which owner your trying to create the folder and you can change the owner of the folder to the current logged in

chown (“root/folder/”,"owner_name");//giv the proper owner name

--if your not able to create due to group permission then

-pls check under which group your trying to create the folder and you can change the group of the folder to the current logged in

chgrp (“root/folder/”,"group_name");//giv the proper group name

- if you’re not able to create due to safe mode on

-if your trying to create recursive folders in linux server then u must take care of safemode setting inside your config file

-if your server safemode is ON then your unable to create recursive folders

It wont alow you to change the permission through php script by default it vl take its own apache as user and group as apache

-to overcome this prblem you can try this by changing the safemode off through php like this

ini_set("safe_mode",0);

-if your using .htaccess file at ur root level then you can try the by setting

Default safe_mode off ;

-in worst condition if the above 2 way don’t work then you have to switch of the safe mode directly inside your apache server configure so by this your php should be able to create folder inside linux server

Uploading Multiple Files in PHP without ajax or jquery

2009-10-06T05:07:00.000-07:00

Uploading Multiple Files in PHP without ajax or jquery

Here iam giving simple and very efficient php multiple file uploader in single submit with the option of deleting uploaded files from the list

And this uploader works in both LE and Firefox very well

While uploading multiple file after adding files into the list before uploading u can able to alter the list in this uploader, and in list only the file names will be visible

And inside javascript u can change the images and buttons based on your require

The Steps installing this uploader into ur php file pls follow the steps below

Step 1

Paste this following javascript inside ur html file or in separate javascript file which should be include in html

function MultiSelector( list_target, max ){

// Where to write the list

this.list_target = list_target;

// How many elements?

this.count = 0;

// How many elements?

this.id = 0;

// Is there a maximum?

if( max ){

this.max = max;

} else {

this.max = -1;

};

/**

* Add a new file input element

this.addElement = function( element ){

// Make sure it's a file input element

if( element.tagName == 'INPUT' && element.type == 'file' ){ // Element name -- what number am I?

element.name = 'ufile[]';//this u can set if your making use of array in the list

element.id='ufile[]'; // Add reference to this object

element.multi_selector = this;

// What to do when a file is selected

element.onchange = function(){

// New file input

var new_element = document.createElement( 'input' );

new_element.type = 'file';

new_element.size = '48';

// Add new element

this.parentNode.insertBefore( new_element, this );

// Apply 'update' to element

this.multi_selector.addElement( new_element );

// Update list

this.multi_selector.addListRow( this );

// Hide this: we can't use display:none because Safari doesn't like it

this.style.position = 'absolute';

this.style.left = '-1000px';

};

// If we've reached maximum number, disable input element

if( this.max != -1 && this.count >= this.max ){

element.disabled = true;

};

// File element counter

this.count++;

// Most recent element

this.current_element = element;

} else {

// This can only be applied to file input elements!

alert( 'Error: not a file input element' );

};

/**

* Add a new row to the list of files

this.addListRow = function( element ){

// Row div

var new_row = document.createElement( 'div' );

// Delete button to add the button

var new_row_button = document.createElement( 'input' );

new_row_button.type = 'button';

new_row_button.value = 'Delete';

new_row_button.align = 'absbottom';

new_row_button.style.cursor = 'hand';

// Delete image instead of button you can put image with this following code

/*var new_row_button = document.createElement('img');

new_row_button.src = images/image_namegif';

new_row_button.alt = 'Delete';

new_row_button.height = '14';

new_row_button.align = 'absbottom';*/

// References

new_row.element = element;

// Delete function

new_row_button.onclick= function(){

// Remove element from form

this.parentNode.element.parentNode.removeChild( this.parentNode.element );

// Remove this row from the list

this.parentNode.parentNode.removeChild( this.parentNode );

// Decrement counter

this.parentNode.element.multi_selector.count--;

// Re-enable input element (if it's disabled)

this.parentNode.element.multi_selector.current_element.disabled = false;

// Appease Safari

// without it Safari wants to reload the browser window

// which nixes your already queued uploads

return false;

};

// Add button

new_row.appendChild(new_row_button);

// Set row value

var arr = element.value.split("\\");

var out_count =arr.length;

if(navigator.appName == "Microsoft Internet Explorer") {

var new_label = document.createElement('label');

new_label.align = 'absmiddle';

new_label.innerHTML = ' '+arr[out_count - 1];

//new_row.innerHTML += arr[out_count - 1];

new_row.appendChild(new_label);

//new_row.innerHTML = new_row_button;

}

else

{

var new_label = document.createElement('label');

new_label.align = 'absmiddle';

new_label.innerHTML = ' '+element.value;

new_row.appendChild(new_label);

}

//new_row.appendChild(new_row_button);

// Add it to the list

this.list_target.appendChild( new_row );

};

Step 2

Paste this code in place of where you want to display the upload browse button and the list of file uploaded

Hav form with action

<form action="upload.php"   method="post" id="uploadfrm" name=" uploadfrm " enctype="multipart/form-data">

<div >

<input id="ufile[]" size="48" type="file" value="" name="file_1" />

</div>

<div id="files_list"> </div>//here you can see the list of files uploaded

</form>

Step 3

In upload.php you can access this files data in this way

if (count($_FILES ['ufile']['name'])) {

for($i=0;$i

{

$root_path= //root path of the upload folder where you created

$path[$i]= $root_path."/upload/".$_FILES['ufile']['name'][$i];//where you want to upload the your files(path) $file_names[$i] = $_FILES['ufile']['name'][$i];

$copy_done[$i] = copy($_FILES['ufile']['tmp_name'][$i], $path[$i]);

}

if($copy_done)

{

echo "uploaded";

}

How to get full url path in php by using server parameter

2009-09-10T03:34:00.000-07:00

From $_server variable has several parameter related to get the url information in different format

Getting the url information from the $server depends on in which way you want to display information like getting only server host or server request url ,server port etc…..

Here iam giving some information about getting url information in different ways in different cases.

-To get server host name

.echo $_SERVER['HTTP_HOST'];

-To get server name

echo $_SERVER['SERVER_NAME'];

-To get server port

echo $_SERVER["SERVER_PORT"];

By using the above predefined variables we can able to get the full u rl of the present page in which ur working

Here is example to get the full url in php

/**
*
* @to get the full url of page on which ur working
*
*/
function getUrlAddress()
{
/*** check for https is on or not ***/
$url = $_SERVER['HTTPS'] == 'on' ? 'https' : 'http';
/*** return the full address ***/
return $ url .'://'.$_SERVER['HTTP_HOST'].$_SERVER['REQUEST_URI'];
}

/*** example usage ***/
echo getUrlAddress ();

Naming Conventions & Coding Standards in PHP.

2009-08-19T02:58:00.000-07:00

Naming Conventions & Coding Standards in PHP.

Naming Conventions

PHP Files

Names should be short & descriptive (either in German or English).
If the module is handling a DB table, then its name should be same as the table itself omitting ‘table_’.

Templates

Name of template should be identical to the name of the php module with change in extension to ‘.tpl’ or .html
If there is more than one template, then use postfix like ‘_xyz” to the template name. Eg : ‘user_header.tpl’ & ‘user_position.tpl’ or .html

Functions

Function name should be in English.
Only Lower case letters to be used.
Should contain 2 parts

Appropriate Verb ( Eg. get)
Manipulated Object( Eg. Product )
Eg : get_students() | get_ students _name()
A short description about the output and input parameters should also accompany the function description.

Classes

Class Names

Camel Case convention should be followed.
Beginning letter should be in Caps

Variable Names

Local variables : All small letters with ‘_’ for separation.
Local Methods : Camel Case with beginning letter in ‘Small Caps’.

Variable Names inside PHP code/modules

Use Lower Case Letters only
Use ‘_’ for separation.

Coding & Documentation

1. A DocBlock / Documentation Block.

A basic DocBlock looks like this:

/**

**/

To document any function, place the DocBlock immediately before the function declaration.

A DocBlock contains three basic segments in this order:

· Short Description

· Long Description

o The Short Description starts on the first line, and can be terminated with a blank line or a period. A period inside a word (like example.com or 0.1 %) is ignored. If the Short Description would become more than three lines long, only the first line is taken. The Long Description continues for as many lines as desired and may contain html markup for display formatting. Here is a sample DocBlock with a Short and a Long Description:

§ Example :

/**

* return the date of Easter

* Using the formula from "Formulas that are way too complicated for anyone to

* ever understand except for me" by Irwin Nerdy, this function calculates the

* date of Easter given a date in the Ancient Mayan Calendar, if you can also

* guess the birthday of the author.

· Tags

o Optionally, you may enclose all paragraphs in a

tag.

o Be careful, if the first paragraph does not begin with

, phpDocumentor will assume that the DocBlock is using the simple double line break to define paragraph breaks as in Example:

/**

* Short desc

Long description first sentence starts here

* and continues on this line for a while

* finally concluding here at the end of

* this paragraph

* This text is completely ignored! it is not enclosed in p tags

This is a new paragraph

2. TAGS

* Here are the tags:

* @abstract

* @access public or private

* @author author name

* @copyright name date

* @deprecated description

* @deprec alias for deprecated

* @example /path/to/example

* @exception Javadoc-compatible, use as needed

* @global type $globalvarname

* @global type description of global variable usage in a function

* @ignore

* @internal private information for advanced developers only

* @param type [$varname] description

* @return type description

* @link URL

* @name procpagealias

* @name $globalvaralias

* @magic phpdoc.de compatibility

* @package package name

* @see name of another element that can be documented,

* produces a link to it in the documentation

* @since a version or a date

* @static

* @staticvar type description of static variable usage in a function

* @subpackage sub package name, groupings inside of a project

* @throws Javadoc-compatible, use as needed

* @todo phpdoc.de compatibility

* @var type a data type for a class variable

* @version version

3. Other Considerations

a. Usage of space

i. For enhancing readability, spaces should be used between each function name , command , commas and brackets

b. Prevent lines with excess length.

i. Code should be readable in editors with normal number of character ( 80 or 100 max). Horizontal scrolling should be avoided.

ii. Example

$sql = sprintf ("SELECT %s FROM %s WHERE %s='%s'",

$field_value,

$table,

$field_index,

$id

);

And not like this one:

$sql = sprintf ("SELECT %s FROM %s WHERE %s='%s'", field_value, $table,$field_index, $id);

c. Positioning Of Brackets

i. If Statement

If (“ “)

{

….

}

Else

{

…

}

ii. Switch Statement

Switch(“ “)

{

case 1 :

line 1;

line 2;

break;

case 2 :

line 3;

line 4;

break;

}

d. Documenting Rule

i. Do not comment on things which are obvious.

ii. As a matter of principle , the variable name should give away the meaning of the same eliminating unwanted documentation.

iii. Make clear why a certain action is taken. As shown in the example :

/**

* An unregistered customer calls up a product

**/

If (isset($_SESSION["user"])==false)

{

/**

* All unregistered caller gets a temporary customer ID. If he registered during his

* session, all statistical data is to be rewritten on to his correct ID.

**/

if (isset ($_SESSION["tmpStudentID "])==false)

{

....

}

e. Documentation of implementation details and background

i. Its recommended that the developer documents the background details which are taken up for granted.

/**

* We are using a timer of seconds, risking the problem of two customers using the

* same function at the same second, not to be identified.

**/

$time = time();

$ StudentrID = $time;

$_SESSION["tmpStudentID"]=$StudentrID;

How to reload page based on number of seconds

2009-08-19T02:27:00.000-07:00

How to reload page based on number of seconds

In case in any page if you want to reload the page for every 5 sec. then use this simple code to reload the page in different way.

The reloading page can be done in many ways like html, javascript and PHP

In HTML

As basic in html page itself you can change meta data to reload the page in some seconds

The following example shows

Ex-1:

//<meta http-equiv="Refresh" content="5">

Waits for 5 seconds to reload the page

Ex-2:

//<meta http-equiv="Refresh" content="10;url=index.html"

Waits for 10 seconds to reload the page and redirect the page to index.html

In PHP

From php page reload of page can be done in this way

Ex:

     $page = $_SERVER['PHP_SELF'];
   $sec = "5";
   header("Refresh: $sec; url=$page");
 ?>
  Here the $page can give you the current page information and the $sec  gives you the seconds for how long the page  should waits
In JAVASCRIPT
The same reloading can be done in javascript with the following code
Ex:
        Here the javascript will be define with the function 
 function Re_load() {
 window.location ='http://index.php'
And the calling this javascript function onload of the body inside 
//onload="timer=setTimeout(‘Re_load ()',3000)"
So after 3000 milisec the page will reload automatically

Proxy setting in apache or Url with out port number

2009-07-27T02:06:00.000-07:00

Here you can see the example for proxy setting in your apache or redirecting your site in to other site with in your apache configuration

You may facing problem of getting port number in url when your having same server with different port usually by default your server will be set to port 80 if you are having a different site on same server but with different port if you try to run site u will get the port number in url this may be looking ugly. So here is solution to over come this problem

The below example shows you how do proxy setting in apache

Ste1. enable proxy module in side your apache configuration file (http.conf) in side conf folder

LoadModule proxy_module modules/mod_proxy.so

#LoadModule proxy_ajp_module modules/mod_proxy_ajp.so

#LoadModule proxy_balancer_module modules/mod_proxy_balancer.so

LoadModule proxy_connect_module modules/mod_proxy_connect.so

LoadModule proxy_http_module modules/mod_proxy_http.so

Step2. paste the following code inside http.conf

ProxyRequests off

Order deny,allow
Allow from all

ProxyPass /site1 http://www.example.com/stie1

Like this you can have different site in single port number first time when you enter www.example.com this is basic site if user mention www.example.com/stie1 then this should goes to different application

How to remove port number from url

Here you may be getting your site url like this example:8222/index.php problem here is you may be having different site on same server but with different port number .but this looks ugly… to remove the port number from the url use the same method of proxy

Order deny,allow
Allow from all

ProxyPass /site1 http://example:8222/stie1

When you enter the www.example.com this proxy setting will redirect your site to the site1 folder but the url name remain same as www.example.com

How to Create image file and get image Resource like image height and width in PHP

2009-07-21T05:02:00.000-07:00

How to Create image file and get image Resource like image height and width in PHP

In some case u may need the image height or width or image resolution in php function to check weather these image suites with your site or not…..

The following function gives the list

-width of image

-height of image

-resolution of the image

-how to create the image file inside your php

-how to get the image Resource

-hoe to get Extension of image file etc….

To get all this image related resource call the below function

echo $image_width = getImageWidth(/image/path/image.jpg)//here the correct image path should give

function getImageWidth($filename){

if(file_exists($filename))

{

$ext = getExtension($filename);//to get the image extension its defined bellow

if(!$ext)

return 0;

$img_src = getImageResource($ext, $filename);//to get the image resource its defined bellow

return imagesx($img_src);

}

return 0;

}

function getImageHeight($filename){

if(file_exists($filename))

{

$ext = getExtension($filename);

if(!$ext)

return 0;

$img_src = getImageResource($ext, $filename);

return imagesy($img_src);

}

return 0;

}

To get the image Extension here is the function

function getExtension($filename)//the filename is path of the image

{

if($filename == '')

return false;

$ext = substr( $filename, strrpos( $filename, "." )+1 );

return $ext;

}

To get the image resource to get the image width or height

So the following function gives you the resource of the image type

function getImageResource($ext, $filename)//the image extension and the image path should be given

{

$imageresource = '';

if($ext == "jpg" || $ext == "JPG" || $ext == "jpeg" || $ext == "JPEG"){

$imageresource = imagecreatefromjpeg($filename);

}

if($ext == "gif" || $ext == "GIF"){

$imageresource = imagecreatefromgif($filename);

}

if($ext == "bmp" || $ext == "BMP"){

$imageresource = imagecreatefromwbmp($filename);

}

if($ext == "png" || $ext == "PNG"){

$imageresource = imagecreatefrompng($filename);

}

/*if(!$imageresource){//if not valid image

return false;

}*/

return $imageresource;

}

And finally how to create image file by using the extension , image resource and destination filename. The following function create image file with this parameters

Parameter list for the function

//here $ext is extension of the image

//$imgresource is the resource of the image with the width and height this you can get by $dst_im = imagecreatetruecolor($width, $height);

//$dest_filename is the destination file name where you want to save the file

function createImagefile ($ext, $imgresource, $dest_filename)

{

$imgfile = false;

if($ext == "jpg" || $ext == "JPG" || $ext == "jpeg" || $ext == "JPEG"){

$imgfile = imagejpeg($imgresource, $dest_filename);

}

if($ext == "gif" || $ext == "GIF"){

$imgfile = imagegif($imgresource, $dest_filename);

}

if($ext == "png" || $ext == "PNG"){

$imgfile = imagepng($imgresource, $dest_filename);

}

if($ext == "bmp" || $ext == "BMP"){

$imgfile = imagewbmp($imgresource, $dest_filename);

}

/*if($imgfile)

return true;*/

return $imgfile;

}

The native windows dinding for php

2009-06-20T04:16:00.000-07:00

WinBinder is a new open source extension for PHP, the script programming language. It allows PHP programmers to easily build native Windows applications. Click here for more information.

Some key benefits

A small set of WinBinder functions encapsulates many complex aspects of the Windows API and makes programming for Windows an easy task.
No compiling and linking steps necessary: just code and run.
Interfaces directly to the Window API. This means fast execution, no extra libraries and no installation required.
Access to the vast range of existing PHP functions and extensions, including databases, graphics, web functions, XML, PDF, and much more.

Creating WinBinder applications

There are five steps needed to create a WinBinder application:

Create the main window.
Create controls for the main window.
Create a handler function to process the controls.
Assign the handler function to the main window.
Enter the application loop.

Example

The simple example below creates a very basic WinBinder application with two button controls. The comments show the required steps.

include "../include/winbinder.php"; // Location of WinBinder library // STEP 1: Create main window $mainwin = wb_create_window(NULL, AppWindow, "Five steps", 320, 240); // STEP 2: Create controls for the main window Geometry data Id wb_create_control($mainwin, PushButton, "Button 1", 50, 70, 80, 22, 101); wb_create_control($mainwin, PushButton, "Button 2", 180, 70, 80, 22, 102); // STEP 3: Create a handler function to process the controls (see below). // STEP 4: Assign the handler function to the main window. wb_set_handler($mainwin, "process_main"); // STEP 5: Enter application loop wb_main_loop(); // The handler function from step 3 function process_main($window, $id) { switch($id) { case 101: case 102: wb_message_box($window, "Button #$id was pressed."); break; case IDCLOSE: // The constant IDCLOSE is predefined wb_destroy_window($window); // Destroy the window break; } }

Setting up Editor by using TinyMCE

2009-05-30T00:04:00.000-07:00

Adding Editor in your page is noe really very easy……

By adding the TinyMCE plugins and javascript its very easy to set editor

TinyMCE is a platform independent web based Javascript HTML WYSIWYG editor control released as Open Source under LGPL by Moxiecode Systems AB. It has the ability to convert HTML TEXTAREA fields or other HTML elements to editor instances. TinyMCE is very easy to integrate into other Content Management Systems.

This example displays all plugins and buttons that comes with the TinyMCE package.

So before adding this example into ur page download the TinyMCE package from the following links…..

Useful Smarty TIPS

2009-05-22T06:13:00.000-07:00

smarty new release

Smarty allows access to PHP objects through the templates. There are two ways to access them. One way is to register objects to the template, then use access them via syntax similar to custom functions. The other way is to assign objects to the templates and access them much like any other assigned variable. The first method has a much nicer template syntax. It is also more secure, as a registered object can be restricted to certain methods or properties. However, a registered object cannot be looped over or assigned in arrays of objects, etc. The method you choose will be determined by your needs, but use the first method whenever possible to keep template syntax to a minimum.
If security is enabled, no private methods or functions can be accessed (begininning with "_"). If a method and property of the same name exist, the method will be used.
You can restrict the methods and properties that can be accessed by listing them in an array as the third registration parameter.
By default, parameters passed to objects through the templates are passed the same way custom functions get them. An associative array is passed as the first parameter, and the smarty object as the second. If you want the parameters passed one at a time for each argument like traditional object parameter passing, set the fourth registration parameter to false.

Ex, using a registered or assigned object
register_object("foobar",$myobj);
// if we want to restrict access to certain methods or properties, list them
$smarty->register_object("foobar",$myobj,array('meth1','meth2','prop1'));
// if you want to use the traditional object parameter format, pass a boolean of false
$smarty->register_object("foobar",$myobj,null,false);

// We can also assign objects. Assign by ref when possible.
$smarty->assign_by_ref("myobj", $myobj);

$smarty->display("index.tpl");
?>

TEMPLATE:

{* access our registered object *}
{foobar->meth1 p1="foo" p2=$bar}

{* you can also assign the output *}
{foobar->meth1 p1="foo" p2=$bar assign="output"}
the output was {$output)

{* access our assigned object *}
{$myobj->meth1("foo",$bar)}

Useful Smarty TIPS
Default Variable Handling
f a variable is used frequently throughout your templates, applying the default modifier every time it is mentioned can get a bit ugly. You can remedy this by assigning the variable its default value with the assign function
{* do this somewhere at the top of your template *}
{assign var="title" value=$title|default:"no title"}

{* if $title was empty, it now contains the value "no title" when you print it *}
{$title}

Blank Variable Handling

There may be times when you want to print a default value for an empty variable instead of printing nothing, such as printing " " so that table backgrounds work properly. Many would use an {if} statement to handle this, but there is a shorthand way with Smarty, using the default variable modifier.
{* the long way *}

{if $title eq ""}

{else}
{$title}
{/if}

{* the short way *}

{$title|default:" "}

Dates in smarty

As a rule of thumb, always pass dates to Smarty as timestamps. This allows template designers to use date_format for full control over date formatting, and also makes it easy to compare dates if necessary.
NOTE: As of Smarty 1.4.0, you can pass dates to Smarty as unix timestamps, mysql timestamps, or any date parsable by strtotime().
{$startDate|date_format}

OUTPUT:

Jan 4, 2001

{$startDate|date_format:"%Y/%m/%d"}

OUTPUT:

2001/01/04

{if $date1 < $date2} ... {/if} When using {html_select_date} in a template, The programmer will most likely want to convert the output from the form back into timestamp format. Here is a function to help you with that. // this assumes your form elements are named // startDate_Day, startDate_Month, startDate_Year $startDate = makeTimeStamp($startDate_Year,$startDate_Month,$startDate_Day); function makeTimeStamp($year="",$month="",$day="") { if(empty($year)) $year = strftime("%Y"); if(empty($month)) $month = strftime("%m"); if(empty($day)) $day = strftime("%d"); return mktime(0,0,0,$month,$day,$year); } Componentized Templates

Traditionally, programming templates into your applications goes as follows: First, you accumulate your variables within your PHP application, (maybe with database queries.) Then, you instantiate your Smarty object, assign the variables and display the template. So lets say for example we have a stock ticker on our template. We would collect the stock data in our application, then assign these variables in the template and display it. Now wouldn't it be nice if you could add this stock ticker to any application by merely including the template, and not worry about fetching the data up front?
You can embed PHP into your templates with the {php}{/php} tags. With this, you can setup self contained templates with their own data structures for assigning their own variables. With the logic embedded like this, you can keep the template & logic together. This way no matter where the template source is coming from, it is always together as one component.
{* Smarty *}

{php}

// setup our function for fetching stock data
function fetch_ticker($symbol,&$ticker_name,&$ticker_price) {
// put logic here that fetches $ticker_name
// and $ticker_price from some resource
}

// call the function
fetch_ticker("YHOO",$ticker_name,$ticker_price);

// assign template variables
$this->assign("ticker_name",$ticker_name);
$this->assign("ticker_price",$ticker_price);

{/php}

Stock Name: {$ticker_name} Stock Price: {$ticker_price}

Creating xml files

2009-05-21T05:47:00.000-07:00

creating xml file as output of your php file execution can be done by using php parser
-here in terms of object the xml file can be created.…..

The xml file will be created on bases of the class object u created……each tag will be having separate object….
creating xml file consist of following steps

Step 1)create object class of the table from which your going to access data.

The following sample shows how to create the class obj
/*
* This class insert or fetches values from/to XML file.
*/

class Class_name //giv table name as class name for better working
{
private $id;
private $name;

public function getId() //get function for accessing the data
{
return $this->id;
}

public function setId($param)//set function to insert data into the table
{
$this->id = $param;
}
.
.
.etc…

}
?>
Step2)in this step just copy this parser code and paste in new php file and name it as “parser.php “ this following code consist of create and getAll function. Where create function creates the xml file by using obj of the class which u created by using table
And the getAll function is used to get the data from the xml file which u created.

include_once "Class_name.php"; // the object class which u created
class Parser
{
public static function getAll($file) //to get data from the xml object
{
if(file_exists($file.'.xml'))
{
$objxml = new Parser;
$xmlobj = simplexml_load_file($file.".xml");
$class_name = ucfirst($xmlobj->class_name);
$obj = new $class_name();
foreach ($objxml->getClassMethods($class_name) as $method)
{
$length = strlen($method);
$field = substr($method, 3, $length);
$type = substr($method, 0, 3);
if($type == 'set')
{
$field = strtolower($field);
$obj->$method($xmlobj->$field);
}
}
$object[] = $obj;
return $object;
}
else
{
return false;
}
}

public static function create($obj, $file) //to create the xml file
{
$objxml = new Parser;
$class_name = $objxml->getClass($obj);
foreach ($objxml->getClassMethods($class_name) as $method)
{
$length=strlen($method);
$field=substr($method, 3, $length);
$type=substr($method, 0, 3);
if($type=='get')
{
$field = strtolower($field);
$val[$field] = $obj->$method();
}
}
$objxml->xml_file_create($val, $file, $class_name);
}

public function create_xml_nodes($obj, $array)
{
foreach($array as $key => $value)
{
if(is_array($value))
{
$parentobj = $obj->addChild($key);
$this->create_xml_nodes($parentobj, $value);
}
else
{
$obj->addChild($key, $value);
}
}
}
private function xml_file_create($data, $file, $class_name)
{
$fp = fopen($file.".xml","w");
$xmltext = "\n";
$xmlobj = simplexml_load_string($xmltext);
$xmlobj->addChild("class_name", $class_name);
foreach($data as $key => $value)
{
if(is_array($value))
{
$parentobj = $xmlobj->addChild($key);
$length = strlen($key);
$key = substr($key, 0, $length-1);
foreach($value as $val)
{
$childobj = $parentobj->addChild($key);
$this->create_xml_nodes($childobj, $val);
}
}
else
{
$xmlobj->addChild($key, $value);
}
}
//Writing on to file.
fwrite($fp, $xmlobj->asXML());
fclose($fp);
}

private function getClassMethods($classname) //to access the class obj
{
$methods = array();
if (!class_exists($classname))
{
throw new Exception ("Class $classname does not exists.");
}
$reflector = new ReflectionClass($classname);
$reflected_methods = $reflector->getMethods();

foreach ($reflected_methods as $reflected)
{
$methods[] = $reflected->getName();
}

return $methods;
}

private function getClass($instance)
{
$reflector = new ReflectionObject($instance);

if (!$reflector->isInstance($instance))
{
return false;
}

return $reflector->getName();
}
}
?>

Step3)In next step create the example php file as “test.php “which consist of calling create and getAll function…with example…..

require_once 'Parser.php';
$parser = new Parser;

$tpl = new Class_name();
$tpl->setId("100");//u can give any id or pass any value wich
$tpl->setName("TESTNAME");

$parser->create($tpl,"xmlfile"); //here “xmlfile” is the name in which xml file will be created

// the following function is optional if u want to display the content of the xml file then the following code will work based on the obj class and the xml tags will be created on obj….
$data = $parser->getAll("tpl_sample_4");//takes file name as input.
echo "Id :: ".$data[0]->getId().'
';
echo "Name :: ".$data[0]->getName().'
';
//print_r($array);

?>

The out put of this test.php is

Id :: 100
Name :: TESTNAME

Understanding Python

ABSTRACT

The Python language, while object-oriented, is fundamentally different from both C++ and Java. The dynamic and introspective nature of Python allow for language mechanics unlike that of static languages. This talk aims to enlighten programmers new to Python about these fundamentals, the language mechanics that flow from them and how to effectively put those to use. Among the topics covered are duck-typing, interfaces, descriptors, decorators, metaclasses, reference-counting and the cyclic-garbage collector, the divide between C/C++ data and Python objects and the CPython implementation in general.

This talk is part of the Advanced Topics in Programming Languages series. The goal of this series is to encourage all of the people at Google who know and love programming languages to share their knowledge. If you would like information on upcoming talks, or to schedule a talk of your own, contact information is available on the wiki page:

A Starter Language

Are you a newcomer to programming? Python is an ideal first language. It originated in a 1980s project to design a language for beginners. Its maintainers have always shown a willingness to "do things right." The Python world understands that phrase to mean they make the language logical, simple, and inviting, even at the occasional expense of conflict with industry traditions.

Python insiders don't just talk about "outreach" to non-programmers. The Python community supports an active "Programming for Everybody" Special Interest Group. Python founder Guido van Rossum's current principal project, funded by the Department of Defense's Advanced Research Project Agency, is on the same topic.

The Python features newcomers most applaud include:

*

Its availability: There's no charge for using Python, and essentially identical versions are available for Windows, MacOS, Linux, BeOS, other Unixes, and many other operating systems.
*

Its interactivity: Once installed, a Python user can immediately interpret his work. Type a line of source code, and Python processes it as soon as you hit "Enter." That short feedback loop is especially important for beginning programmers.
*

Its simplicity: Guess what

current = 2000
start = 1990
elapsed = current - start
print elapsed

does. You're right -- and you've just read your first Python program. Python minimizes unpleasant surprises and "trickiness."
*

Its power: Python developers typically report they are able to develop applications in a half to a tenth the amount of time it takes them to do the same work in such languages as C. While "power" and "expressivity" seem to have unquantifiably subjective components, experts generally agree that Python has as much or more of these good things as other languages.

Scalability

Scalability is nerdspeak for "travels well and doesn't let me down." While Python is great for beginners, it also fills the needs of expert users. Other languages popular in educational settings have been scorned by working developers as too slow, incapable of connecting to existing resources, or too inflexible. Few complain about Python in these regards. Python stretches all the way from beginners' one-liners to some of the largest and most demanding computer programs. Python is in use, for example, as part of very complex supercomputer analyses of metal fractures.

We need to be careful about several key concepts in understanding Python's capabilities "on the high end." The metal structure application just mentioned uses Python in crucial ways; in fact, insiders have said that the project simply wouldn't have succeeded without Python. However, most large Python-coded programs, including this one, have a majority of their source written in such other languages as FORTRAN, Java, C, and C++.

Each of these other languages is superior in certain aspects: speed, scientific calculation, graphics manipulation. Each also has characteristic weaknesses. The search for the one true language to use for complex projects is a mistake. The more rational approach is to find the right mix of languages and "glue" them together with Python. You will end up with more efficient, error-free, and maintainable code by using Python to combine the best of each of these.

Because it plays nicely with other languages, Python doesn't create dead-ends. While this idea is hard to make precise, experienced programmers recognize it. Programs begun in Python have good lives; they don't hit limits in speed or algorithmic sophistication which cause them to stagnate. They grow with your needs and your abilities. I almost always feel safe in choosing Python for a project. Even when information turns up during the life of the project that was unknown at the beginning, I have confidence that Python's flexibility will accommodate new needs and constraints.

For technical reasons, also, Python's "object-oriented" syntax has proven to be excellent for teamwork. Experience has shown that engineers working in different areas, and even the same programmers returning to old programs, read unfamiliar Python source code comfortably. This is Python's greatest strength in my own work. As a highly-expressive, object-oriented, well-structured, interoperable language, it promotes the success of large complex projects in a way no other language does.
