Cameron Olthuis wants to share the tools that he finds th emost useful with the entire web, so he's posted them here on his blog.
His list includes libraries from all different technologies, not just PHP. Several are Javascript-related, but it's always good to have a complete toolkit on hand when trying to tackle some of the more difficult things.
Included in his list are things like:
- Moo.fx - a Javascript effects library
- Swat - an open source web application toolkit
- PEAR - the PHP package repository
- Mochikit - lightweight Javascript library
