$_GET -- $HTTP_GET_VARS [deprecated] — HTTP GET variables
An associative array of variables passed to the current script via the URL parameters.
$HTTP_GET_VARS contains the same initial information, but is not a superglobal. (Note that $HTTP_GET_VARS and $_GET are different variables and that PHP handles them as such)
| Version | Description |
|---|---|
| 4.1.0 | Introduced $_GET that deprecated $HTTP_GET_VARS. |
Example #1 $_GET example
<?php
echo 'Hello ' . htmlspecialchars($_GET["name"]) . '!';
?>
Assuming the user entered http://example.com/?name=Hannes
The above example will output something similar to:
Hello Hannes!
Note: This is a 'superglobal', or automatic global, variable. This simply means that it is available in all scopes throughout a script. There is no need to do global $variable; to access it within functions or methods.
Note: The GET variables are passed through urldecode().
