Check out the predefined global variable $_SERVER. It is an array that contains most of the info you request.

Check it out and put the following in a page:

PHP Code:

<?php

print_r($_SERVER);

?>

Try this script, it is similar to the one I use on Good Scripts

PHP Code:

 class getuserinfo{
 function getuserinfo()
     {
         /* This gets info about the user's system: Browser, OS, Bots etc. */
         if (is_array($_SERVER)) {
             $ua = $_SERVER["HTTP_USER_AGENT"];
         } else {
             global $HTTP_SERVER_VARS;
             $ua = $HTTP_SERVER_VARS["HTTP_USER_AGENT"];
         } 
 
         /* Bot Check */
         $this->botname = '';
         $bots = Array('Google', 'Slurp', 'Scooter', 'Spider', 'Infoseek',
             'Ask Jeeves', 'slurp@inktomi', 'whatuseek', 'Is_Archiver');
         for($i = 0;$i < count($bots);$i++) {
             if (eregi($bots[$i], $ua)) {
                 $this->botname = $bots[$i];
                 break;
             } 
         } 
         if (eregi("bot", $ua) && empty($this->botname)) {
             $this->botname = "Other";
         } 
 
         /* No bot? Then check what the user's browser is */
         if (!empty($this->botname)) {
             $this->browser = "Bot";
         } elseif ((ereg("Nav", $ua)) || (ereg("Gold", $ua)) || (ereg("X11", $ua)) || (ereg("Mozilla", $ua)) || (ereg("Netscape", $ua)) AND (!ereg("MSIE", $ua) AND (!ereg("Konqueror", $ua)))) {
             $this->browser = "Netscape";
         } else {
             $browsers = Array("MSIE", "Lynx", "Opera", "WebTV", "Konqueror", "Other");
             for($j = 0;$j < count($browsers);$j++) {
                 if (eregi($browsers[$j], $ua)) {
                     $this->browser = $browsers[$j];
                     break;
                 } else {
                     $this->browser = "Other";
                 } 
             } 
         } 
         /* Check what the OS is */
         $n_os = Array("Win", "Mac", "PPC", "Linux", "FreeBSD", "SunOS", "IRIX", "BeOS",
             "OS/2", "AIX");
         $r_os = Array("Windows", "Mac", "Mac", 1, 1, 1, 1, 1,
             1, 1);
         for($i = 0;$i < count($n_os);$i++) {
             if (eregi($n_os[$i], $ua)) {
                 $this->os = ($r_os[$i] == 1) ? $n_os[$i] : $r_os[$i];
                 break;
             } else {
                 $this->os = "Other";
             } 
         } 
         return true;
     } 
 }
 
 $user = new getuserinfo(); 

The variables can then be accessed through:

PHP Code:

 $user->os; // Operating system.
 $user->browser; // Web browser.
 $user->botname; // If there is a bot, the name of it. 

I have not tried this version but it should work!

Hi there,

If you are seriously eager to learn about these stats things, I would recommend that you try a book about HTTP. Here's one by C. Shiflett that I use:

HTTP DEVELOPER'S HANDBOOK
http://shiflett.org/books/http-developers-handbook

I admit that this book will be an "overkill" if all you need is identifying the users' browser, referer, etc. BUT if you are to continue web developing further, sooner or later, you may find this book helpful.
