this is old subject everyone is tired of i'm sure. but since large changes have been made to call_user_func[_array] recently, i want to confirm: if an object calls one of its methods ($thing->foo()), any static-type method calls made inside there - self::a(), parent::a(), fezbar::a() - will have $this defined, pointing to original calling object. self:: and parent:: are always relative to the containing class, regardless of this. two exceptions: - the method is declared as 'static'; if so, $this is never set - the method is called via call_user_func or call_user_func_array; if so, $this is not set the very last part seems like it *might* be a bug, or it might be a decision - that call_user_func(array('class','function'),$arg) will always force class::function() to behave as if declared statically. that is a bit of a problem for self:: and parent:: but that is ok if it is how it must be. if anyone can say about this, it would be kind. ps - i looked in old mail, sure this had been discussed - topic came up, but nothing for sure, except introduction of 'static' to prevent $this, which solves opposite problem :)
