PHP Superglobals Hack : alexking.org

I’ve added my superglobals hack to tasks. The code looks like this:

This file (superglobals.inc.php) is included in each function that references a superglobal:

<?php

// for PHP versions < 4.1, will use the
// vars defined in compatibility.inc.php
if (!$_REQUEST || !$_SESSION || !$_SERVER || !$_COOKIE) {
    global $_REQUEST, $_SESSION, $_SERVER, $_COOKIE;
}
?>

The superglobals are defined in another file (compatibility.inc.php) which is included at the top of the rendering pages:

<?php

if (!$_REQUEST) {

    $_REQUEST = $HTTP_GET_VARS;

    $_REQUEST = array_merge($_REQUEST, $HTTP_POST_VARS);

    $_REQUEST = array_merge($_REQUEST, $HTTP_COOKIE_VARS);

}

if (!$_SESSION) {

    $_SESSION = $HTTP_SESSION_VARS;

}

if (!$_SERVER) {

    $_SERVER = $HTTP_SERVER_VARS;

}

if (!$_COOKIE) {

    $_COOKIE = $HTTP_COOKIE_VARS;

}

?>

You can include the $_POST, $_GET and $_FILES vars (etc.) if you use them.

This all seems to work, if you know of a problem with this technique, post a comment or let me know
