Regardless of whether it's used for validation (which I agree is a bad idea), type errors may still occur elsewhere in the code; being able to handle those errors using exceptions has the advantage of keeping the context; a custom error handler lacks this and wouldn't be able to distinguish between errors, let alone be able to show the end-user any decent feedback. > > -- > PHP Internals - PHP Runtime Development Mailing List > To unsubscribe, visit: http://www.php.net/unsub.php > > -- -- Tjerk
