The current technologies we have today and the numerous improvements to the PHP programming language, makes our legacy applications operate "below today’s standards". They need to be improved or rewritten, but who would want to rewrite an application of many thousands or millions of lines of code?

That’s why you should read this book, ‘Modernizing Legacy Applications in PHP’ by Paul M. Jones. It explains the nitty-gritty of how PHP applications were built over a decade ago and why they are now called legacy applications. He explains why your legacy applications are not meant to be rewritten, but optimized and improved to support today’s standards.

The reviewer goes through each chapter of the book, giving an overview of each including topics discussed and a few of the handy tips. Overall he recommends the book not only to those experienced in the industry but also those new to developing in PHP, helping to prevent bad behaviors before they start.
