    $retval = ereg("(\.)(com$)", $email_id);
    if( $retval == true )
    {
       echo "Found a .com<br>";
    }
    else
    {
       echo "Could not found a .com<br>";
    }
    $retval = ereg(("(\.)(com$)"), $email_id, $regs);
    if( $retval == true )
    {
       echo "Found a .com and reg = ". $regs[0];
    }
