Detecting Ajax Request with PHP Script

Here’s a script that useful to check if a request that comes to a PHP page was made via an Ajax call or a simple form post. This method uses the $_SERVER['HTTP_X_REQUESTED_WITH'] request to determine if data was sent to a specific page using an xmlhttprequest.The script is pretty self explanatory,we are checking to see if the request was sent via an xmlhttprequest.

Example Script :

if(isset($_SERVER['HTTP_X_REQUESTED_WITH']) && !empty($_SERVER['HTTP_X_REQUESTED_WITH']) && strtolower($_SERVER['HTTP_X_REQUESTED_WITH']) == 'xmlhttprequest')
{
// If its an ajax request execute the code below
echo 'This is an ajax request!';
exit;
}
//if it's not an ajax request echo the below.
echo 'This is clearly not an ajax request!';

Automatic Load a page Using Ajax

Here we can learn about how to Automatically load page after 5 second using ajax and jquery.First we get little information about Ajax.
AJAX = Asynchronous JavaScript and XML.
AJAX is not a new programming language, but a new way to use existing standards.
AJAX is the art of exchanging data with a server, and updating parts of a web page - without reloading the whole page.

Example script :
Create two files :
1) main file
2) load file
create main.php this is main file.

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" 
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.3.0/jquery.min.js">
</script>
<script>
 setInterval(
function()
{
$('#content').fadeOut('slow').load('load.php').fadeIn("slow");}, 3000);
</script>
<title>Auto Load Page Div using Jquery - similar to twitter Live Search</title>
</head>
<body>
<div id="content" style="background-color:#ffffcc;font-size:24px;font-weight:bold;width:600px;margin:auto 10px;">

Please wait.</div>
<a href="#" target="_blank">Home</a>
</body>
<html>

The second file is load.php this file load every 5 second.

echo 'This content is loaded via ajax every 5 seconds ..';
