我常用的自定义函数之clean php自动过滤功能

常在系统开始加载时引入
if (ini_get('magic_quotes_gpc')) {//php5.4以上版本直接返回false
function clean($data) {
if (is_array($data)) {
foreach ($data as $key => $value) {
$data[clean($key)] = clean($value);
}
} else {
$data = stripslashes($data);
}

return $data;
}

$_GET = clean($_GET);
$_POST = clean($_POST);
$_REQUEST = clean($_REQUEST);
$_COOKIE = clean($_COOKIE);
}
