Dear internals, I stumbled upon the following odd error message from PHP which I was not expecting. function test(){

    echo $this == $this->c1->c2?'equals':'not equals'; // Somehow this

Use === (shallow test - returns true iff the variables refer to the same instance) instead of == (deep comparision - member-by-member). Still in theory it should not produce an error.

Yes, it should. == is going to test all the properties of the object against each other. So to compare. $this == $this->c1->c2, it will compare $this->c1 == $this->c1->c2->c1, which will in turn compare $this->c1->c2 == $this->c1->c2->c1->c2, which in turn compares $this->c1->c2->c1 == $this->c1->c2->c1->c2->c1 And so on. -- --Robert Deaton
