The PHP built-in $_POST function is used to collect values in a form (as name says, you do this with the method=”post”) The information send with POST method is invisible to others (the opposite of the GET method.)
Another difference between the $_GET function and the $_POST function is that the $_POST function doesn’t limit the amount of information that you want to send. (Limit of $_GET is 100 characters.)

The setting is called post_max_size.) More »
