Is it not in the scope of the class function?

[PHP] function within a class function

Forgive my ignorance but I have absolutely no idea what you're trying to tell me. usort() is part of the language so when, why, how does it become an object of some class? -- We have rights, as individuals, to give as much of our own money as we please to charity; but as members of Congress we have no right so to appropriate a dollar of public money. -- David Crockett Rick Pasottor...@niof.nethttp://www.niof.net -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
