Re: __call overload detection

If you need more it is up to you to provide the infrastructure. Remember we will not in anyway allow __call to handle inheritance.

Hi Marcus, If one is determined enough, at least visibility can be faked by exception trace introspection. Below demonstrates protected, replace __CLASS__ with get_class($this) for private. I see very little or no real world application for this and the procedure is quite expensive. <?php class Test {

    public function __construct() {
        // demo, should echo "hello"
        echo $this->nonexistant;
    }

    public function __get($offset) {
        try {
            throw new Exception();
        } catch (Exception $e) {
            $trace = $e->getTrace();
            $caller = isset($trace[2]['class']) ? $trace[2]['class'] : null;
            if ($caller === null
                || $caller != __CLASS__
                && !is_subclass_of($caller, __CLASS__)) {
                    throw new Exception('Access to protected ' .__CLASS__. '::' .$offset. ' from context '. $caller);
            }
        }

        return 'hello';
    }

}

$t = new Test();           // hello
echo $t->nonexistant;      // exception
