I think it's a stupid idea (actually OO is a stupid idea but that's something for another dicussion ;-): 1. In order to silently ignore failed queries you still have to put a stupid try..except block around it. 2. KISS: PHP is supposed to be SIMPLE; with all thos advanced OO stuff writing scripts for PHP starts becoming less and less easy. Sure, they are already using OO but that's just a notation. Some extensions are only OO, like DOM, but that doesn't mean that every Joe Average has any idea on what exceptions are. Please, kepe things simple. Don't force people.

Derick, The fact that you have something personal against OOP doesn't mean it's not good. I think that functional context should continue to work as usual, but there's a big advantage to be able to catch problems with try/catch and not have to if() each internal function call separately (which you probably don't do :) I don't see a problem with OOP extensions throwing exceptions.

I like OO (*), and I think warnings (non-fatal errors) as exceptions are a stupid idea. Does that count? ;-) Exceptions in languages like Java are used explicitly to catch fatal errors, not to catch basic errors. Converting warnings to exceptions would change the meaning of a warning from something which is nice for development, or logging purposes, but handled by your control flow, into an unrecoverable error. Errors as exceptions are a different story. I don't think that's a bad idea at all. But leave good alone, warnings shouldn't be exceptions. -Sterling (*) Though my like is most definitely due to stockholm syndrome, and excessive brainrape. Nonetheless. :)
