4	* Invoker Class — Overview and Usage Guide
5	*
6	* What is the Invoker class?
7	*
8	* The Invoker class is a utility helper that allows you to access and
9	* manipulate private and protected properties and methods of PHP
10	* objects and classes at runtime. It uses PHP’s Closure
11	* binding and Reflection API under the hood.
12	*
13	* This is especially useful when working with third-party or legacy code where
14	* you don’t have control over visibility or public APIs, but still need to
15	* read/write internal state or call hidden methods for testing,
16	* debugging, or extending functionality.
17	*
18	* Key Features:
19	* - Access private/protected instance properties
20	* — read or modify values not exposed publicly.
21	*
22	* - Call private/protected instance methods
23	* — invoke internal methods not accessible otherwise.
24	*
25	* - Access private/protected static properties on classes.
26	* - Call private/protected static methods on classes.
27	* - Unified static API for all operations
28	* — no need to instantiate the Invoker class.
29	*
30	* - Direct closure binding through invoke() for custom, complex access scenarios.
31	*
32	* When to use the Invoker class?
33	* - When you need to test or debug classes with private/protected members.
34	* - When working with third-party libraries or legacy code where
35	* you can't change visibility.
36	*
37	* - For unit tests that require access to internal state or behaviors.
38	* - When you want to extend or patch behavior of an existing
39	* class without modifying its source.
40	*
41	* - When you want to inspect or manipulate class internals safely without
42	* reflection boilerplate scattered everywhere.
43	*
44	*
45	* Examples of using Invoker:
46	*
47	* // Access private/protected instance properties
48	* $value = Invoker::get($object, 'propertyName');
49	* Invoker::set($object, 'propertyName', $newValue);
50	*
51	* // Call private/protected instance methods
52	* $result = Invoker::call($object, 'methodName', [$arg1, $arg2]);
53	*
54	* // Access private/protected static properties
55	* $value = Invoker::getStatic(ClassName::class, 'staticProperty');
56	* Invoker::setStatic(ClassName::class, 'staticProperty', $newValue);
57	*
58	* // Call private/protected static methods
59	* $result = Invoker::callStatic(ClassName::class, 'staticMethod', [$arg1, $arg2]);
60	*
61	* // Use custom closure binding for complex scenarios
62	* $result = Invoker::invoke($object, function () {
63	* // $this references the bound object instance
64	* return $this->somePrivateProperty + 42;
65	* });
