I have down-loaded several php scripts and am working my way through them
as part of my learning process. I have noticed situations like this:

mysql_query("DELETE FROM $table WHERE id=$id",$db);

where scripts have been called from another script/page with a parameter -
i.e. 'id' is a parameter that is not defined in the script before the
above line is called.

They don't work as they are but I can get the parameters by using
$_GET['id'] or sometimes $_POST['id'].

Is this a result of different versions of php (I am using v5) where
behaviour has changed or is it something else that is going completely
over my head because I am so new to this?

Many thanks.
