Apply a function on multiple variables

[nomad9]

Hi!

just found this script to prevent bad form entry :

function clean($input){
$input = strip_tags($input);
$input = htmlspecialchars($input);
$input = addslashes($input);
$input = trim($input);
return $input;
}

but if i've got 4 field in my form :

$firstName = $REQUEST['firstName'];
$lastName = $REQUEST['lastName'];
$from = $REQUEST['email'];
$message = $REQUEST['message'];

how can i easely run the fouction on each variable ????

$firstName = clean($firstName);
$lastName = clean($lastName);
$from = clean($from);
$message = clean($message);

is it the proper way to do it ???

Unless you want to pass a variable-sized array to clean().
