Operating System

[Anon]

Using PHP how can I tell what browser and operating system people are using when they access my website?

Look in the code gallery in here (phpbuilder.com) and zend.com, and you'll find scripts that can detect browsers and OSs.

In the PHP manual http://us2.php.net/manual/en/reserved.variables.php

Somewhere there, you can find information on getting the Operating System, etc. there.

Here's a snippet:

HTTP_USER_AGENT

Contents of the User_Agent: header from the current request, if there is one. This is a string denoting the user agent being which is accessing the page. A typical example is: Mozilla/4.5 [en] (X11; U; Linux 2.2.9 i586). Among other things, you can use this value with get_browser() to tailor your page's output to the capabilities of the user agent.

Then you can whip up whatever type of script you would like.
