Hello, I thought I would post this here for others to use.

This is a script that will spit out all the data contained in the following variables:

$_SERVER, $_COOKIE, $_ENV, $_REQUEST, $_POST, and $_GET

Then at the bottom of the page, there are 2 links back to the same page, one with a query string, one without. Also there are two forms, one a POST, one a GET, each with sample of form items.

This can be nice for checking things or just seing what you can get from the variables.

Enjoy!
