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; 
} 
?>
