Something doesn't have to be "wrong", another approach can just be more convenient, or handy for different use cases. One class one file can be rather slow depending on the autoloader setup, and depending on whether zend optimizer is enabled or not. For a distributed application running on mostly crap shared hosting, relying on Zend Optimizer is not an option, so the more of these little one-class one-file situations you have the worse it becomes. This RFC offers a solution for people that is not "Jam a bunch of these classes at the top of the current file" or "Make a whole load of one-time use classes to avoid that mess, plus people will snort and shame you for failing to follow decade old best practices." -- PHP Internals - PHP Runtime Development Mailing List To unsubscribe, visit: http://www.php.net/unsub.php
