"PHP Design Patterns" first introduces design patterns, describes the use and importance of design patterns, and explains in detail the occasions when design patterns are applied. Next, the book introduces many design patterns through code examples. Finally, this book explains through comprehensive and in-depth case studies how to use design patterns to plan new applications, how to write these patterns in PHP language, and how to use the design patterns introduced in the book to modify and refactor existing code blocks. The authors present concepts in a professional, user-friendly format that will be familiar to both self-taught programmers and those with more formal training.
PHP is often regarded as the cornerstone for building flexible and feature-rich web applications. Because it is relatively easy to learn, novice programmers can easily create applications from scratch using PHP. However, given the size of these applications, the maintenance effort is daunting. Fortunately, the mature programming community has provided some solutions, including design patterns. These repeatable solutions to the same problems have been used in other programming languages ​​for many years. The goal of PHP Design Patterns is to tie PHP to earlier programming languages ​​by applying proven design patterns to PHP applications.
