PHP5下$_SERVER变量不再受magic_quotes_gpc保护的弥补方法

<?php
$magic_quotes_gpc = get_magic_quotes_gpc();
@extract(daddslashes($_COOKIE));
@extract(daddslashes($_POST));
@extract(daddslashes($_GET));
if(!$magic_quotes_gpc) {
$_FILES = daddslashes($_FILES);
}

//转译字符函数
function daddslashes($string) {
if(!is_array($string)) return addslashes($string);
foreach($string as $key => $val) $string[$key] = daddslashes($val);
return $string;
}
?>
