You need another closing brace before the "?>" to close the final else block.

You need to actually call the function...

ini_set ('display_errors', 1);
error_reporting (E_ALL & ~E_NOTICE);
// check an email address is possibly valid
if (isset ($_POST['submit']{
    validateEmail($_POST['address']);
}
else
{
    print '<form action="handle_reg.php" method="post">
        <p>EMAIL: <input type="text" name="address" size="20" /></p>
        <input type="submit" name="submit" value="validate" />
        </form>';
}

function validateEmail($address)
{
    if(empty($address))
    {
        echo 'No Address Given';
        return;
    }

// This regex pattern lifted from user-notes at php.net
$domain = '([a-z0-9]([-a-z0-9]*[a-z0-9]+)?)';
$atom = '[-a-z0-9!#$%&\'*+/=?^_`{|}~]';
$pattern = '^' . $atom . '+' . '(\.' . $atom . '+)*' . '@' . '(' . $domain . '{1,63}\.)+' . $domain . '{2,63}' . '$';

if(!eregi($pattern, $address))
{
    echo 'Address Validation Failed!';
}
else
{
    echo 'Address Is Valid!';
}
return;
}

Hope that helps.
