Because it's a string. You can use regex matching or test whether floor($var) == $var, for example. Steve At 4/29/2001 04:25 AM, Jamie Saunders wrote:

Hi, I'm submitting a phone number from an HTML form to a PHP page that examines it to see if it's an integer: form.html: validate.php: <?php $phonenumber = trim($phonenumber); if (is_int($phonenumber)) { echo "Integer"; } else { echo "Not Integer"; } ?> However, for some reason the script doesn't recognize the number as an Integer - why is this and how can I remedy it?
