Is there a $_SERVER variable I can use to see what was sent through a form? For example, if I have a form, and I want to log what a user submits through that form in a separate file, what could I do?

Example:

User types in their username/password in a form
Script intercepts that data, and records it to a file (all but password, of course )

Thanks!

$_POST['key']

I know I could do that, chrishirst xD

Basically I'm making a script that will sit in one file and watch what people send to and from the server. It intercepts it, writes it to a log file, then sends it on it's way.

If you only want to record from one form (or a couple) and you have access to the processing code, do it in code. If lots of forms or no code access, either access all network traffic or do it with an Apache plugin (so no longer a php question).

Ah, ok thanks Paul!
