 Do not use stripslashes 
 
 
 
if (GET_MAGIC_QUOTES_GPC ())        {function Stripslashes_deep ($value) {$value = Is_array ($value)?        Array_map (' Stripslashes_deep ', $value): Stripslashes ($value);     return $value;     } $_post = Array_map (' Stripslashes_deep ', $_post);     $_get = Array_map (' Stripslashes_deep ', $_get); $_cookie = Array_map (' Stripslashes_deep ', $_cookie);}
