Bug description: is_callable / __call interaction
Description:
------------
Long story short, I created a class factory class. I have singleton
classes which this class handles beautifully, except for non-singleton
classes which use __call.
All singleton classes have a method named "Singleton". If this method
exists, I invoke the Singleton method via call_user_func (which I noticed
call_user_func doesn't route to __call, though that's in the bug DB).
Though I understand how __call is supposed to work and I love how it
works, I feel there needs to be some sort of differentiation between
classes that are explicitly defined in the class file vs what's being
routed to __call.
I spent a good 3 hours scouring the online PHP documentation to find a
solution that already exists for this, so my only assumption is that one
doesn't exist. It would be a real asset to the function is_callable (or a
separate function) to be able to check for explicitly defined methods that
do not use __call.
I think it is valuable to be able to have the option for is_callable to be
able to detect methods that are callable via __call. I feel it is also
absolutely necessary that methods that can't be called without __call can
be detected properly as well.
Reproduce code:
---------------
class CClass
{
public function __constructor () {}
public function __call ($_function, $_arguments)
{}
}
$_className = 'CClass';
if (is_callable (array ($_className,'Singleton')))
$class = call_user_func (array($_className, 'Singleton'));
else
$class = new $_className ();
Expected result:
----------------
I would expect no fatal errors because PHP took a dump reporting singleton
doesn't exist when hitting call_user_func.
Actual result:
--------------
Fatal error: Call to undefined method CURL_Wrapper::singleton() in
/home/webos2/public_html/WebOS2/WebOS2.php on line 75
is_callable states the class method exists regardless of the situation
when using __call in a class.
