From my understanding it's not limited to PHP, but part of how forms are used
with HTML. Information can be sent through a form with input fields (using the
post method), or can put the information in the URL (using the get method) that
you described. With the get method you normally have the script name, followed
by a "?" and the parameters added after it, such as

http://domain.com/form.php?param1=1&param2=t

In PHP you would use the $_GET['param1'] and $_GET['param2'] to get those
values. The "?" just provides another way to send the information to a program.
