Bug description:ReflectionParameter::isDefaultValueAvailable inconsistent for
Closure
Description:
------------
When calling ReflectionParameter::isDefaultValueAvailable() on
Closure::__invoke()
as an object method, it returns the incorrect value. However, when calling
it on
a closure as a function, it returns the correct value. Examples below.
Test script:
---------------
<?php
/**
* the expected behavior from an object
*/
class Foo
{
public function __invoke($baz = 'qux')
{
return $baz;
}
}
$object = new Foo;
var_dump(is_object($object)); // true, so PHP thinks it's an object
$method = new ReflectionMethod($object, '__invoke'); // object method
exists
$params = $method->getParameters();
var_dump($params[0]->isDefaultValueAvailable()); // true
/**
* now test a closure
*/
// note the default value
$closure = function ($baz = 'qux') {
return $baz;
};
// treat it as an object: available = false (unexpected)
var_dump(is_object($closure)); // true, so PHP thinks it's an object
$method = new ReflectionMethod($closure, '__invoke'); // object method
exists
$params = $method->getParameters();
var_dump($params[0]->isDefaultValueAvailable()); // false
// treat it as a function: available = true (expected)
$func = new ReflectionFunction($closure);
$params = $func->getParameters();
var_dump($params[0]->isDefaultValueAvailable()); // true
Expected result:
----------------
I figured, since PHP seems to think the Closure is an object, that one
could get a
correct isDefaultValueAvailable() from reflecting on __invoke() as an
object
method (in this case, boolean TRUE).
Actual result:
--------------
It returns boolean FALSE when reflecting on Closure::__invoke() as an
object
method.
