Elements within the >array are reflected as global variables and vice-versa. Let's refine the conceptual example: class Hello { private $_world = 'World'; function __construct(){} } $GLOBALS['hello'] = new Hello(); echo 'The variable $hello is '.gettype($hello)."\n".print_r($hello,true); Can we then postulate that the value of $GLOBALS['hello'] will also be revealed in $hello, even though $hello was never formally declared? I know that $GLOBALS['hello'] has a universal scope, and $hello (wherever it comes from) needs to be global-ized inside functions.
