Bug description:ReflectionMethod::invoke() on non-abstract ancestor
Description:
------------
Consider a situation when an abstract class (or an interface) is defined
and a
concrete class that extends it. If we get instantiate a ReferenceClass
object for
the abstract class (or the interface), we can then get an ReferenceMethod
instance
for the abstract method.
Unfortunately, calling the ReferenceMethod::invoke() method for an instance
of the
concrete class throws a ReflectionException ("Trying to invoke abstract
method...").
Test script:
---------------
<?php
abstract class A
{
public abstract function doA();
}
interface IB
{
function doB();
}
class B extends A implements IB
{
public function doA()
{
echo 'A is done.';
}
public function doB()
{
echo 'B is done.';
}
}
$b = new B();
$b->doA();
$b->doB();
$refA = new \ReflectionClass('A');
$refDoA = $refA->getMethod('doA');
$refDoA->invoke($b);
$refIB = new \ReflectionClass('IB');
$refDoB = $refIB->getMethod('doB');
$refDoB->invoke($b);
?>
Expected result:
----------------
The invocation of the method on an instance of the concrete class should
succeed.
Actual result:
--------------
PHP Fatal error: Uncaught exception 'ReflectionException' with message
'Trying to
invoke abstract method ...()' in ...:..
