Implementing email address validation

[Haddy]

Any tips for implementing the email address validation class? My php
output blanks out whenever I try to initialize the class...

<?php
include("EmailAddressValidator.php");

$validator = new EmailAddressValidator;

// errors out here, no output. Removal of class declaration enables
output...

?>

To get this working, I simply removed all class functionality, all the
public and private function declarations and put those functions at
the top of my file.
