Description:
------------
When checking variables either not declared or after having unset() them with empty() or isset(), some errors occure.
In former times, empty() and isset() have not produced errors - even if it is a NOTICE now.
-> hopefully this is not the way it is meant to be - I think, than it's not only me who has to rewrite his code

Reproduce code:
---------------
class test {
	function __construct() {
		if (empty($this->test[0][0])) { print "test1";}
		if (!isset($this->test[0][0])) { print "test2";}
	}
}

$test1 = new test();

Expected result:
----------------
test1test2

Actual result:
--------------
Notice: Undefined property: test::$test in D:\inetpub\wwwroot\fmwars\temp.php on line 41

test1Notice: Undefined property: test::$test in D:\inetpub\wwwroot\fmwars\temp.php on line 42

test2
