ReflectionCallable

It supports 6 types of callable object. (ref. Wani Blog, Callable), _(*4)

1. string of function's name.
2. string of class and static method's name.
3. array of class and static method's name.
4. array of object and method's name.
5. object of class that has __invoke method. (ref. Magic Method __invoke)
6. object of Closure.

and two more., _(*5)

1. __call magic method.
2. __callStatic magic method.

Example.

use Wandu\Reflection\ReflectionCallable;

// 1. string of function's name.
$reflection = new ReflectionCallable('yourfunctionname'); // OK
$reflection = new ReflectionCallable('Your\OwnNamespace\yourfunctionname'); // with namespace also OK.

// 2. string of class and static method's name.
$reflection = new ReflectionCallable('Your\OwnNamespace\MyClass::callMyMethod'); // OK

// 3. array of class and static method's name.
$reflection = new ReflectionCallable(['Your\OwnNamespace\MyClass', 'callMyMethod']); // OK

// 4. array of object and method's name.
$reflection = new ReflectionCallable([new Your\OwnNamespace\MyClass(), 'callMyMethod']); // OK

// 5. object of class that has `__invoke` method.
$reflection = new ReflectionCallable(new Your\OwnNamespace\ClassWithInvoke()); // OK

// 6. object of `Closure`
$reflection = new ReflectionCallable(function ($param1, $param2) { /* do something */ });

$reflection->getNumberOfParameters(); // return 2

// 7. __call
$reflection = new ReflectionCallable([new Your\OwnNamespace\HasCallClass, 'anything']);

$reflection->getNumberOfParameters(); // always return 0
$reflection->getNumberOfRequiredParameters(); // always return 0
$reflection->getParameters(); // always return []
$reflection->getShortName(); // return 'anything'
$reflection->getName(); // return 'anything'

// 8. __callStatic
$reflection = new ReflectionCallable([Your\OwnNamespace\HasCallStaticClass::class, 'anything']);

$reflection->getNumberOfParameters(); // always return 0
$reflection->getNumberOfRequiredParameters(); // always return 0
$reflection->getParameters(); // always return []
$reflection->getShortName(); // return 'anything'
$reflection->getName(); // return 'anything'
