In previous tutorials we already looked at the PHP built-in $_GET function and $_POST function. In this tutorial we take a quick look at the PHP built-in $_REQUEST function.

The PHP built-in $_REQUEST function can be used with both the GET and POST methods. More »

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.) But you should be aware of the following: by default there is an 8Mb maximum size for the post method. (If you want a larger size you can change it in the php.ini file. The setting is called post_max_size.) More »
