v.1 Forsome reason this program doesnt do the else case in which the phone number is valid
v.2 fixed, problem was in the ordering of }'s

<?php
    if(isset($_GET['submit'])) {
      if(preg_match("/^\(([2-9][0-9]{2})\)[2-9][0-9]{2}-[0-9]{4}$/i",
              $_GET['phone']) != 1) {
        echo "The phone field was invalid<BR>";
        }
       else {
        echo "The phone field was valid.  Good job!<BR>";
        }
      }
    ?>
