[SOLVED] Reading all the URL parameters

[Rauldinho]

Hi, i wanted to know how i can read all the parameters coming from the URL in PHP. For example:

 

www.something.com?a=1&b=2&c=3

and then in a php file i have something like a cycle that gives me an output like this:

First Parameter: a is 1

Second Parameter: b is 2

Third Parameter: c is 3

 

Thanks for any help, hope i made myself clear!

ok, i think i didn't explain myself completely. What i want is to GET all those parameters but i don't know how many of them are. I want to make a cycle that goes through the URL and gives me all the parameters that were sent. thank you for answering
