Appendix C. Extending and Embedding Cookbook

C Extending and Embedding Cookbook

LIKE A WELL APPOINTED KITCHEN, PHP OFFERS THE ENVIRONMENT and ingredients necessary to create any masterpiece that accomplished chefs puts their mind to. As anyone who has spent time over a stove knows, however, it's not enough to simply toss some ingredients into a blender at random and pop the resulting glop into the microwave. An enjoyable meal, much like a usable extension, requires a recipe. In the preceding chapters, you learned the basic skills you need to create some of these recipes from scratch, but there's no reason to start from square one on most tasks. This appendix offers some examples of common use code that you can reuse in your own extension or embedding projects.
