Gareth Heyes' Blog:
Regular expression challenge
October 19, 2007 @ 14:48:00

Gareth Heyes has posted another challenge to his blog - this time it involves using a regular expression to convert the inputted string into the output he's given.

After the success of my "a bit of fun" challenge, a few people asked for some more challenges. So I was answering a question on a mailing list that I'm a member of and I thought it would be a good topic for a little challenge and help sharpen everyone's regular expression skills.

This time, his challenge involves taking the input, rail start/end locations from an array and, via the PHP script given (no regular expression in it, of course) make the output, a sort of JSON formatted message. It's already been answered, but if you want to, try it yourself first then read the answer below the post.
