Why would the libraries writers use the checks inside the method instead of the typing, even in the case of the weak typing? I don't see a single reason to do so, because if they ask for an "int" in the method signature, they will get an int or the method won't get called at all. See the example in the RFC with the "if (!is_int($i))". Pavel Kouril -- PHP Internals - PHP Runtime Development Mailing List To unsubscribe, visit: http://www.php.net/unsub.php
