Bug description: difference between call_user_func(array($this, $method)) and
$this->$method()
Description:
------------
There is a difference in behavior of call_user_func(array($this, $method))
and $this->$method() while class B inherits from class A and both declares
the same method. The call_user_func() function seems to work as expected,
but using $this->$method() seems to invoke parent method implementation
instead of the overridden one.
Reproduce code:
---------------
class A
{
protected function Test()
{
echo 'Hello from '.get_class($this);
}
public function call($method, $args = array())
{
return $this->$method();
//return call_user_func(array($this, $method));
}
}
class B extends A
{
protected function Test()
{
echo 'Overridden hello from '.get_class($this);
}
}
$a = new A;
$b = new B;
$a->call('Test');
$b->call('Test');
Expected result:
----------------
Hello from A
Overridden hello from B
Actual result:
--------------
Hello from A
Hello from B
