Description:
------------
method_exists() has a weird behavior when used on anonymous functions.
One would expect that testing the variable that holds the anonymous
function and the class of the anonymous function (Closure) to either
have or not the __invoke method. Instead method_exists() reports that
the variable that holds the anonymous function HAS an __invoke method
and the class of the anonymous function HAS NOT an __invoke method. Is
this behavior correct? If yes, maybe somebody can explain why. Thank you
in advance.
Test script:
---------------
<?php
$lambda = function() {};
var_dump( method_exists( $lambda, '__invoke' ) );
var_dump( method_exists( get_class( $lambda ), '__invoke' ) );
Expected result:
----------------
boolean(false)
boolean(false)
or
boolean(true)
boolean(true)
Actual result:
--------------
boolean(true)
boolean(false)
