[PEPr] Comment on PHP::PHP_Callback

Johannes Schlüter (http://pear.php.net/user/johannes) has commented on the proposal for PHP::PHP_Callback. Comment: Ok, I don't really care but I think one point was missed in this whole discussion: How often do you really need a general purpose callback mechanism? In my experience my "callbacks" need to handle specific parameters or something like that. But these aren't checked by this package. But there's a technology in PHP which is quite good for this: It's called "interfaces". IN places I want to have a custom callback I expect a object implementing a specific interface and call a method on that. In cases where you need a special purpose callback one should also think on the API usability - it's nice to think on developers of PEAR classes but I think it's way more important to think on the average user using the package. I think every PEAR user knows PHP callbacks (from usort(), preg_replace_callback(), ....) so using that should be straight forward. But using PHP_Callback the user first has to find out what PHP_Callback is and how to use it and as a user, not being interested in implementation details, this looks "strange". Feel free to ignore my comment - I won't vote anyways :-) Proposal information: http://pear.php.net/pepr/pepr-proposal-show.php?id=482 -- Sent by PEPr, the automatic proposal system at http://pear.php.net
