Re: exceptions

Hi! I just wanted to place my 2 cents about that topic here. In general I have the feeling, that exceptions are a strong way of flow-controll mechanism. Throw-Try-Catch is obviously a kind of controll structure. For that I would agree with people saying, that Exceptions are a way of conrolling program flow (as e.g. in Java). In PHP we have a special case of the technique of exceptions. Since PHP is a non-compiled (or better to say: a runtime compiled language) you have no chance to see a uncaught exception before run-time or at least before the exceptional state accours. There are IMHO 2 ways to handle this speciallity: a) Each and every throwen exception must be clearly documented besiden the method can be throwen from (this includes exceptions throwen by method's which are used by the class). If this rule is hold, we can use exceptions as flow-controll. b) Use exceptions only for the case of a fatal error. In this case every posible exception should be documented as well, but since an error showen by an excpetion is fatal, a documentation only can help the user to try understanding the error. The latter one is obviously the more logical one. Regards, Toby -- Tobias Schlitt a passion for php http://www.schlitt.info
