PHP $_GET

Introduction

$_GET  is an associative array of variables passed to the current script via query string appended to URL of HTTP request. Note that the array is populated by all requests with a query string in addition to GET requests.

$HTTP_GET_VARS contains the same initial information, but has been deprecated

By default, client browser sends a request for URL on the server by HTTP GET method. A query string attached to URL may contain key=value pairs concatenated by & symbol. The $_GET associative array stores these key value pairs

Example

<?php
echo "Name : " . $_GET["name"] . "<br>";
echo "Age : " . $_GET["age"];
?>

Output

This will produce following result −

Name : xyz
Age : 20
