批量html">過濾post,get敏感數(shù)據(jù)

復制代碼 代碼如下:

$_GET = stripslashes_array($_GET);
$_POST = stripslashes_array($_POST);

數(shù)據(jù)過濾函數(shù)

復制代碼 代碼如下:

function stripslashes_array(&$array) {
 while(list($key,$var) = each($array)) {
  if ($key != 'argc' && $key != 'argv' && (strtoupper($key) != $key || ''.intval($key) == "$key")) {
   if (is_string($var)) {
    $array[$key] = stripslashes($var);
   }
   if (is_array($var))  {
    $array[$key] = stripslashes_array($var);
   }
  }
 }
 return $array; 
}
