Regex Clinic on Slideshare

» 03 May 2010 » In PHP, Talks »

Back in 2004, I submitted a proposal to the only PHP conference ever to have taken place aboard a cruise ship. Yes, the infamous PHP Cruise (“Do we all know each other?”). The talk was about regular expressions and their usage in PHP. I wrote the original version in PowerPoint, but when I boarded the ship and saw Keynote 1.0 on someone’s Powerbook, I was hooked and had to port all the slides to Keynote right then and there.

Well, the talk – and the cruise – went well, and since then Andrei’s Regex Clinic has grown and shrunk in size depending on which conference I was giving it at and how much time was allotted. I considered retiring the talk several times, because surely people should know how to use regular expressions by now, but whenever I give it there is a roomful of people wanting to know what (?>=foo) does. And as much as I try, I always run out of time trying to cover everything from the basics to more advanced usage.

I feel that the slides are pretty polished by now and it’s better if people can read them at a comfortable pace, so the whole tutorial-sized presentation is now available on Slideshare. I omitted the section that covers PHP’s regular expression API, because it already has great online documentation. Otherwise, go forth and read about look-ahead assertions and recursive matching.
