Subject: Re: [PHP-DEV] Re: static/object method
From: alan@akbkhome.com (Alan Knowles)

the E_STRICT warnings on static calls to non static methods are probably 
usefull, (as $this could be defined totally randomly), so it does make 
some sense..

btw: does that mean:

class a { function find() { } }
class b extends a { function find() { } }

// call the toplevel parent method.. (skip the imediate parent)
class c extends b { function find() { a::find() } }
$a = new c;
$c->find();

illicits and E_STRICT warning???

(sorry I havent got the latest PHP5 compiled ATM..)

Regards
Alan
