mysql_real_escape_string() for entire $_REQUEST array, or need to loop through it?

Question

Is there an easier way of safely extracting submitted variables other than the following?

if(isset($_REQUEST[\'kkld\'])) $kkld=mysql_real_escape_string($         


        

Answer 1

If you use mysqli extension and you like to escape all GET variables:

$escaped_get = array_map(array($mysqli, 'real_escape_string'), $_GET);
