this is what i have dont so for but gettting error message.

Warning: preg_match() [function.preg-match]: Unknown modifier '1' in C:\broot\do_redirect.php on line 4

Warning: Cannot modify header information - headers already sent by (output started at C:\Webroot\do_redirect.php:4) in C:\broot\do_redirect.php on line



<?php

  $agent = getenv("http_user_agent");
 if (preg_match ("/msie/1", "$agent")) {
   $result = "you are using microsoft internet explorer.";
 }
 else if (preg_match ("/mozilla/i", "$agent")) {
   $result = " you are using netscape.";
 }
 else {
   $result = "you are using $agent";
 }


// set location if provided from form, else set it to default page:
$location = (!empty($_POST['location'])) ? $_POST['location'] :
            "http://www.msn.com/";
            "http://www.microsoft.com/";
             "http://www.expedia.com/";
              "http://www.aol.com/";
              "http://www.yahoo.com/";
               "http://www.netscape.com/";
// go to that page:
header("Location: $location");
?>

Why you use if or else loop.There is no Need To use this
You simply write this code it will provide you the whole
information about your browser and OS
<?php
 $agent = getenv("http_user_agent");
$result = "you are using $agent";
echo $result;

Hello Dear
You Should Have Declear Header before
any echo/print statment or before any HTML tag
and before Header you can not live any blank line
I hope so it's solve your problem
