Hi, welcome to PHP, and the PHPBuilder.com forums!
Try this:
<?php
//make a PHP script like this:
phpinfo();
?>
You'll see a list of quite a few things that PHP has figured out about its environment. You can use this information in various ways ... for example, you can test what type of browser is looking at the page, or perhaps grab the client's IP address, and so on, and so on....
I'd also recommend a gander at the manual's section on [man]variables[/man] and Predefined variables in particular.....
Have fun with PHP!
