Emanuele Minotto has a recent post with a set of "PHP in a tweet" posts that do all sorts of things.

Yesterday an ex colleague tweeted something that captured my attention, so I started thinking to a Twitter-powered code golfing competition. Looking for other examples.

Tweets included in the list are snippets like:

• A dependency injection container
• A super simple web framework
• A microframework
• Bypassing array_intersect

There's some game rules included in the post so you can contribute your own to the the comments. Several have already been added including a base64 encoding variant and getting the extension of a file.
