Did you read second RFC? The one which is about "so called" weak typehinting. Stas (and a lot of people on this list) prefer it. http://wiki.php.net/rfc/typecheckingstrictandweak If you did, can you tell if there is some case, when it doesn't work for you? The idea is simple: 1) if variable type matches — variable is passed to function 2) if variable can be safely converted to the type, which matches — variable is converted and passed to the function (you still get variable of desired type) 3) if variable can not be safely converted — error is raised error is E_STRICT or E_FATAL (not decided yet). anyway, you can handle it as fatal in error-handler if you need to this way you (library developer) get your desired data-types for input and users get freedom to pass numeric strings instead of numbers good for everyone -- Alexey Zakhlestin http://www.milkfarmsoft.com/ -- PHP Internals - PHP Runtime Development Mailing List To unsubscribe, visit: http://www.php.net/unsub.php
