[Challenge] threads are essentially puzzles. Someone (you!) can post a question that would be interesting to see various solutions to. Just pop [Challenge] in the thread subject somewhere.

When someone posts a [Challenge] thread it'll be linked to here so they're easy to find again:




(Thanks to McInfo for the fancy table thing)

With kudos to ~klevis miho of course for originally coming up with the idea

The moderation team has been discussing ideas for challenges and we think that it's a very good idea. We invite everyone to get involved in solving and coming up with ideas for challenges.

That is great to know. I love to face new "challenges" LOL, although I am not (regretfully) always very good at solving them. But I keep trying ... ;)

How about something practical?

Implement regex-based URL routing: Given a URL, passed by the web server to your front controller, find the most efficient way to match said arbitrary URL against an arbitrarily large list of URL regex's, with an emphasis on avoiding the overhead of repeated preg_match (or similar) calls.

Extra credit: Minimize the number of regex matches while still allowing duplicate named patterns in your URL regex's.

This is a problem I've worked with recently and would be interested in seeing more solutions to.
