Introduction to PHP Extensions

In this presentation, we take a look at writing PHP extensions. Using step-by-step examples, we'll take a function written in PHP and convert it into a loadable extension using C. We'll then test both versions and compare the results. After seeing the size and scope of the benefits that can be realized, you'll want to try it out for yourself. You'll also understand why we start with simple things, and not try to rewrite all of Symfony in C.
