Shouldn't that bug result in some error message by itself? If it doesn't, there's probably nothing to add to "undefined class" anyway.

I meant a logic error - as in the user forgot to use a DIRECTORY_SEPARATOR and so can't find any of the classes, not an obvious PHP error.

GB>>1) document that coders of __autoload() should throw an GB>>autoload_exception if a class is not found Why just not return false or something? Exception is supposed to be used when things are so bad you just can not continue. But I don't think class not being found is such situation for autoload. On the other hand, I think that multiple autoload functions should be evaluated in isoplated way - so that exception, etc. in one of them would terminate it, but not the whole autoload process (i.e., next one would be run).

Perhaps a better solution is to simply augment the "undefined class XXX" method with a brief listing of all the defined __autoload() functions, so the user knows where to look for magic bugs. Greg
