$HTTP_GET_VARS — HTTP GET variables
An associative array of variables passed to the current script via the HTTP GET method.
$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)
If the register_globals directive is set, then these variables will also be made available in the global scope of the script; i.e., separate from the $_GET and $HTTP_GET_VARS arrays. For related information, see the security chapter titled Using Register Globals. These individual globals are not superglobals.
| Version | Description |
|---|---|
| 4.1.0 | Introduced $_GET. Note that the deprecated $HTTP_GET_VARS did exist previously. |
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.
