Call method non-static with static in PHP

Question

i have code look like this:

abstract class Object { public static function __callStatic($name, $parameters) { $object = get_called_class(); $object = new $object; if (method_exists($object, $name)) { return call_user_func_array(array($object, $name), $parameters); } } } class Log extends Object { public function message($message) { echo 'Log: '.$message.'.<br>'; } }

now, i call:

Log::message('test');

this's result:

Strict standards: Non-static method Log::message() should not be called statically...

Log: test.

somebody can help me?

if you want to call message the way you did, just change public function message($message) to public static function message($message) — ponciste

check your php version; the magic method __callStatic() is only available from 5.3.0 — giorgio

__callStatic will work only if your method does not exist. Rename your method from "message" to "messageStatic" and change __callStatic method:

 if (method_exists($object, $name.'Static')) { return call_user_func_array(array($object, $name.'Static'), $parameters); }

Note: __callStatic will also work if the method is declared as protected.

That's because __callStatic() will be triggered only for non-existent methods while your message() method exists and it's non-static.

E.g Log::foo('test'); won't trigger this message since there's no such method.

You're checking your method on existence inside __callStatic() and this has no sense: if __callStatic() was called, it's a call for non-existent method. Thus, condition will always be false and useless.

This may seems odd (because you may wish to call static method as non-static and create instance inside __callStatic()) - but from point of visibility, static and non-static methods are same: thus, if method exists as static it will also be visible as non-static.
