email validation

zoobie

I've set this to validate the email address. If it passes, it sends the email. If it fails, it closes the users browser. One minor prob...not quite working. Fix? Thanks

function valid_email($email) {
    if(ereg("^([0-9,a-z,A-Z]+)([.,_,-]([0-9,a-z,A-Z]+))*[@]([0-9,a-z,A-Z]+)([.,_,-]([0-9,a-z,A-Z]+))*[.]([0-9,a-z,A-Z]){2}([0-9,a-z,A-Z])*$",$email)) {
        return TRUE;
    } else {
        return FALSE;
    }
}

if (valid_email($email)) {
	  $mail_fn=mail($email,$subject,$message_n,$headers);
  }
 else {
        echo "<html><head><script>window.onload = function() {self.opener = this;self.close();}</script></head></html>";
    }

 if($mail_fn==0)
 {
  echo "ERROR";
  }

  else {
     header ("Location: [url]http://site.com/confirm.php[/url]");
         }

Here's the function I use. The getmxrr is optional. Doesn't work on windows platforms.

function checkmail($email) {
   if(eregi("^[_\.0-9a-z-]+@([0-9a-z][-0-9a-z\.]+)\.([a-z]{2,3}$)", $email, $check)) {
      if(getmxrr($check[1].".".$check[2], $temp)) {
         return true;
      }
      else {
         return false;
      }
   }
   else {
      return false;
   }
}
