Calling closure assigned to object property directly
...
As of PHP7, you can do
$obj = new StdClass;
$obj->fn = function($arg) { return "Hello $arg"; };
echo ($obj->fn)('World');
or use Closure::call(), though that doesn't work on a StdClass.
Before PHP7, you'd have to implem...

What is the best way to stop people hacking the PHP-based highscore table of a Flash game
