I don't think this need to be fixed in this way, like __call:

<?php

class Bar {
    private function __call($name, $value) {
        return __CLASS__;
    }
}

$b = new Bar;
$b->__call("name", NULL);

works well, but with an warning:

Warning: The magic method __call() must have public visibility and cannot be static 

I am not sure whether this is a bug, or just need document.

This patch is inconsistent with what actually exist.
Actually, __magics() signature are checked at compile time, not at run-time. This patch adds runtime checks for __invoke() , which IMO is wrong.

I think it's better to stay consistent and add the checks in the zend_compile.c cases.
Visibility is never checked at runtime for __magics() (but used to be).

wrong fix, closed
