When you make a PHP script, but you do not know how PHP is configured on the server the script is being executed on, you might not know whether or not to add or strip quotes from get and post data. Notice that the $_FILES array is not affected by magic quotes.

1. < ?
2. if(get_magic_quotes_gpc()) {
3. function undo_magic_quotes($array) {
4. return is_array($array) ? array_map('undo_magic_quotes', $array) : stripslashes($array);
5. }
6. $_GET = undo_magic_quotes($_GET);
7. $_POST = undo_magic_quotes($_POST);
8. $_COOKIE = undo_magic_quotes($_COOKIE);
9. $_REQUEST = undo_magic_quotes($_REQUEST);
10. }
