Html, reading data after '?'

Question

I am trying to get an HTML/PHP script to interpret data sent after the ? in a url. I've seen sites that do this, YouTube being one of them. I thought this was called Post Data (not sure if it is), I've been searching for a few days, and I can find is the PHP $_POST[''] with some HTML forms reading the data from a textbox, but I would like to read directly from the url, EX. www.example.com?ver=1

How would I go about doing this?

This question should be re-opened. There is nothing ambiguous, vague, incomplete, overly broad, or rhetorical about it. It most certainly **can** be answered in its current form, as evidenced by the two answers (both of which contain up-votes) below. If your reason for voting to close is that you think this is obvious, consider for a moment that your attitude towards questions like this is one of the reasons folks have trouble learning. Sure, a "read the documentation" comment is appropriate, but it isn't a question that should be closed. It's hard for folks to get started sometimes. — Brad, Nov 17 '12 at 04:23

What you're looking for is called a query string. You can find that data in $_GET.

print_r($_GET);

If you need access to the raw data (and you probably don't, unless you need multiples for some variable names), check $_SERVER['QUERY_STRING'].

You can't do that in HTML pages. In PHP pages, you can read (and process) the parameters using the $_GET array. This array contains all the things after which come after ? in the URL. Suppose we have a URL like

page.php?a=b&c=d

Then we can access a and c parameters by $_GET['a'] and $_GET['b']. There is also $_POST which works a bit different. You can google it to find out more.
