This will emulate register_globals On. If you altered your
variables_order directive,
consider changing the $superglobals accordingly.
<?php
// Emulate register_globals on
if (!ini_get('register_globals')) {
$superglobals = array($_SERVER, $_ENV,
$_FILES, $_COOKIE, $_POST, $_GET);
if (isset($_SESSION)) {
array_unshift($superglobals, $_SESSION);
}
foreach ($superglobals as $superglobal) {
extract($superglobal, EXTR_SKIP);
}
}
?>
This will emulate register_globals Off. Keep in mind, that this code
should be called at the very beginning of your script, or after
session_start() if you use it to start your session.
<?php
// Emulate register_globals off
function unregister_GLOBALS()
{
if (!ini_get('register_globals')) {
return;
}
// Might want to change this perhaps to a nicer error
if (isset($_REQUEST['GLOBALS']) || isset($_FILES['GLOBALS'])) {
die('GLOBALS overwrite attempt detected');
}
// Variables that shouldn't be unset
$noUnset = array('GLOBALS', '_GET',
'_POST', '_COOKIE',
'_REQUEST', '_SERVER',
'_ENV', '_FILES');
$input = array_merge($_GET, $_POST,
$_COOKIE, $_SERVER,
$_ENV, $_FILES,
isset($_SESSION) && is_array($_SESSION) ? $_SESSION : array());
foreach ($input as $k => $v) {
if (!in_array($k, $noUnset) && isset($GLOBALS[$k])) {
unset($GLOBALS[$k]);
}
}
}
unregister_GLOBALS();
?>
