Subject: catch of object operations __set and __invoke
From: lpedretti@suserver.com (Leonardo Pedretti)

Hi all.
I have just messed around with the php 5 code so to find a way to implement=
=20
some way to make objects call some magic method when there is an invocation=
=20
of a non existent method, or a setting of a non existent data member (this=
=20
last may not be neccesary by now for what i am implementint, but it would b=
e=20
correct to implement them both).
I have tracked in the zend_execute.c file, line 2507, the call to the error=
=20
when the method is not found, inside the function=20
zend_init_method_call_handler
My question is: the parameter lists in every call is a defined constant... =
it=20
just becomes impossible to backtrack, can someone give me just a bit of=20
information on this topic?
What i think would be correct is that the function that calls=20
zend_init_method_call_handler receives an error in the case the method is n=
ot=20
found, and in that case it calls the handler again calling __invoke() with =
an=20
array of the original parameters and the name of the original function that=
=20
was called. Another method would be to always call __invoke() passing it th=
e=20
original call information, and depending on the return code of __invoke()=20
then execute the original call.
However, I can't find where this hook should be placed around the code. If=
=20
someone can give me a bit of info on this topic, i would love to make the=20
patch.

With regards
=2D-=20
