website.php?site1 whats this called?

[nVRuckus]

I am trying to learn how they do site.com/page.php?site=1ax goes to one set of information and site.com/page.php?site=2ax goes to another, but im not sure what this is called to search for it. Any help would be appreciated.

ps like how this forum has showthread.php?s=xxxxx to show the different threads

It's a superglobal array variebla ($_GET)

So, if you had the following URL:
http://www.domain.com/index.php?variable1=1&variable2=2&variable3=3

then, your GET superglobal array would contain the following values:

$GET['variable1'] = 1
$GET['variable2'] = 2
$_GET['variable3'] = 3

You can verify this by doing a print_r on the $_GET array:

print_r($_GET);

I hope this helps, and gives you ideas on info to search for in the future.
