Call non-static method staticly raise E_STRICT, but why call a static method instancely won't

Hi, I am not sure it's the right place to discuss this. someday I found I call a static method _instancely_. the method is just a helper method when reviewing my code. I know I do the wrong thing, but PHP doesn't complain about it. then I do some tests like below: <?php error_reporting(E_ALL ^ E_STRICT); class A { public function static staticFunc() { echo "static"; } public function instanceFunc() { echo "instace"; } } A::instanceFunct(); // Strict Standards: Non-static method A::instanceFunc() ... $a = new A(); $a->staticFunc(); // Just static no E_STRICT error raised I know it's the wrong way to do like these, maybe there are some historical reasons to allow these. I just wonder why previous method call raise E_STRICT but later not. Yes, something could be done doesn't means we should, but we could stop things like happened. ----- http://reeze.cn
