Check if provided "callback" argument is static

I have a function that takes a "callback" argument. This can be either a function or a static class method.

How can I detect if the method is static or not?

I suppose you could do this with reflection, though this will be slow.

Presuming your callback is $callback:

if (is_array($callback)) { // a function will just be a string
    $classname = $callback[0];
    $methodname = $callback[1];

    $method = new ReflectionMethod($classname, $methodname);

    if ($method->isStatic()) {
        // method is static
    }
}

Note that this doesn't account for times when $callback[0] is an object, or if you have a lambda function as $callback, or probably all kinds of different circumstances. I don't really understand what you're looking for; this may be sufficient.
