as Arvids already pointed out most database extensions for PHP atm return strings even for integers/floats. furthermore the "123abc" example was mentioned more for data coming from external sources, with strict typing you are encouraging stuff like (int)"123abc". Of course a good programmer would first check with is_numeric() before casting. Seems like a lot of work. With the proposal of weak typing with error/notice on data loss none of that would be needed. regards, Lukas Kahwe Smith m...@pooteeweet.org -- PHP Internals - PHP Runtime Development Mailing List To unsubscribe, visit: http://www.php.net/unsub.php
