Globals in PHP differ from many other languages and PHP does not support name space. All global vars are not visible in function or class by default. ( Programmer must declare as global before using it) I recommed you to browse http://www.php.net/docs.php I recommend to set 'enable track vars' and 'disable register globals' in php.ini. If you done this in php.ini, programmer can only access variables from server, browser, etc as acciative arrays like $HTTP_POST_VARS, $HTTP_GET_VARS, $HTTP_SERVER_VARS, $HTTP_UPLOAD_FILES, $HTTP_SESSION_VARS,..... If you want to access POST data from user's browser you can write like function foo() { global $HTTP_POST_VARS; // do something } to access all data that are posted by POST method. (Except $HTTP_UPLOAD_FILES) Using $HTTP_* variables improves code readability I think PS: You can use $GLOBALS[] to access all global vars.
