Introduction to PHP Extensions
You’ve got that need—the need for speed! Using step-by-step examples, we’ll take functions written in PHP and convert them into loadable extensions 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 with only a few minor changes, you’ll be ready to take the plunge. You’ll also understand why we start with simple things, and not try to rewrite all of Symfony in C.
