Globals (global variables) are variables which are valid globally, which means they are available not only in a single function but "generally" throughout the script. register_globals is a switch which is defined in php.ini activating/deactivating this behavior. Since register_globals and the concept of globals is said to be removed for PHP6, it is advised to keep globals off and do not use global variables at all.

Why after installing PHP can it happen that you are able to run PHP functions but not to pass variables?
There are many things that can stop your variables from passing between your forms and your php scripts. One common reason is that your php configuration file is not configured to pass your form variables as globals, and instead passes them through the $_GET and $_POST superglobals. So, for example, if you form is as such: <form method="post"> <input name="whatever"> </form> Your php script would access the variable $whatever through the $_POST superglobal. $whatever = $_POST['whatever'];
