Description:
------------
Static functions don't behave properly at all. They can be called from an object-context and provide no means to even confirm from within the function if it has been called from a static context or not.

I understand that static methods should never have access to $this regardless of context, but unless the engine enforces a restriction on calling static functions from an object context this behavior is completely counter-intuitive and inconsistent. Not only does the engine not catch this, but the developer cannot either.



Reproduce code:
---------------
<?php
        error_reporting(E_ALL);
        class Staticexample {
                const a = 10;

                static function test() {
                        
                        var_dump(isset($this));

                }

                
        }
       
        $b = new Staticexample();
        Staticexample::test();
        $b->test();
        
?>

Expected result:
----------------
bool(false)
bool(true)


Actual result:
--------------
bool(false)
bool(false)
