Re: PEAR's Error Handling and PHP5

Personally, I "port" the PEAR packages I use to PHP5 -- doing things like find/replace on return PEAR::raiseError() ... to throw new PEAR_Exception( and removing any if(PEAR::isError($res)) code. The end result is code that is smaller, easier to read, and less likely to have unhandled errors. But in general, this is true; I write PHP5-only apps, and so all my error handling is PHP5 (i.e. Exception). >> * They don't allow PEAR_Error's tricks such as changing error handling >> (dying, callback, etc), and expecting errors > > Some of this stuff should not be hard to implement when all Exceptions > extend a base PEAR_Exception class and possibly add a function that > handles uncaught exceptions via set_exception_handler(). I haven't yet encountered any case where I felt that PEAR_Exception was insufficient. I have all my exceptions logged while debugging (and adding a listener is great for that), but at some level I know I have to catch them & handle them. > I have yet to see someone bring up a valid reason not to use exceptions. > IMHO, the advantages by far outweigh the tiny little disadvantages one > might see. Obviously, I heartily agree. I'm more than willing to spend an hour grepping through PEAR classes to change the error handling, because it will save me much more time down the road -- and because I can rest easier knowing that my application is handling all my errors in a consistent fashion. There's really no choice in my mind :) That's my .02 on the matter, anyway. Cheers, Hans
