Re: PHP Browser detection

Hi,

The following snippet was taken from the book "PHP Essentials".
(Unfortunately I'm using Php3 on PWS so the preg_match() function generates
a nasty error.)
However, on a unix server it works.

The script will work as is as long as it is the only code in the document.
(No Html at all because the header info can be sent only once. and the
header() function does just that.

<?php

 $browser_type = getenv("HTTP_USER_AGENT");

 if (preg_match("/compatible; MSIE/i", "$browser_type"))


  $location = "http://www.studiodeluxe.net/pws/;

 }else  if (preg_match("/Mozilla/i", "$browser_type")) {

  $location = "http://www.studiodeluxe.net/pws/;

 }else  if (preg_match("/Lynx/i", "$browser_type")) {

  $location = "http://www.studiodeluxe.net/pws/;

 } else {

  $location = "http://www.studiodeluxe.net/shelley/";

 }

 header("Location: $location");
 exit;
?>
