今天找到的一本非常好的书:

PHP Cookbook The PHP Cookbook is a collection of problems, solutions, and practical examples for PHP programmers. The book contains a unique and extensive collection of best practices for everyday PHP programming dilemmas. It contains over 250 recipes, ranging from simple tasks to entire programs that demonstrate complex tasks, such as printing HTML tables and generating bar charts — a treasure trove of useful code for PHP programmers, from novices to advanced practitioners. Who This Book Is For This book is for programmers who need to solve problems with PHP. If you don’t know any PHP, make this your second PHP book. The first should be Programming PHP, also from O’Reilly & Associates. If you’re already familiar with PHP, this book will help you overcome a specific problem and get on with your life (or at least your programming activities.) The PHP Cookbook can also show you how to accomplish a particular task in PHP, like sending email or writing a SOAP server, that you may already know how to do in another language. Programmers converting applications from other languages to PHP will find this book a trusty companion. What Is in This Book We don’t expect that you’ll sit down and read this book from cover to cover. (although we’ll be happy if you do!). PHP programmers are constantly faced with a wide variety of challenges on a wide range of subjects. Turn to the PHP Cookbook when you encounter a problem you need to solve. Each recipe is a self-contained explanation that gives you a head start towards finishing your task. When a recipe refers to topics outside its scope, it contains pointers to related recipes and other online and offline resources. If you choose to read an entire chapter at once, that’s okay. The recipes generally flow from easy to hard, with example programs that “put it all together” at the end of many chapters.The hapter introduction provides an overview of the material covered in the chapter,including relevant background material, and points out a few highlighted recipes of special interest.
