The mechanics of this are somewhat tricky. If you have a function that is passed $a and needs to modify $a you need to declare it as a reference with '&' e.g. -[code]function foo(&$a) { $a->something = 'x'; // whatever }; +[code]function foo(&$a) { App::$something = 'x'; // whatever }; *or* access it within your function as a global variable via get_app() function foo() { $a = get_app(); - $a->something = 'x'; + App::$something = 'x'; } -function foo($a) { $a->something = 'x'; }; +function foo($a) { App::$something = 'x'; }; will *not* change the global app state. function foo() { - get_app()->something = 'x'; + App::$something = 'x'; } [/code] |
