Tedious, and slow because the overhead for each file loaded can easily be in the 2-5ms range. Nobody is going to have a function per file, but they are still likely to use function autoloading in other ways. A likely case for this would be to autoload a group of functions that all share the same prefix. Another case might be to autoload a set of functions that are related to something else (for example, usability of singleton classes would benefit greatly from having a function of the same name as the class, or classes may want to provide a factory function of the same name.)

There is usually only one session, there is only one app, there is usually only one database, logging is usually configured globally, etc. -- PHP Internals - PHP Runtime Development Mailing List To unsubscribe, visit: http://www.php.net/unsub.php
