$this is not empty when calling a static method from within a class:

--cut--
class foo {
    var $a = "A";
    function doit() {
        print $this->a;
    }
}

class bar extends foo {

    function doit() {
        foo::doit();
        print "OK";
    }
}

$b = new bar;
$b->doit();
--cut--

prints AOK.
