Mastering The Faster Web with PHP, MySQL, and JavaScript

By: Andrew Caya

Overview of this book

This book will get you started with the latest benchmarking, profiling and monitoring tools for PHP, MySQL and JavaScript using Docker-based technologies. From optimizing PHP 7 code to learning asynchronous programming, from implementing Modern SQL solutions to discovering Functional JavaScript techniques, this book covers all the latest developments in Faster Web technologies. You will not only learn to determine the best optimization strategies, but also how to implement them. Along the way, you will learn how to profile your PHP scripts with Blackfire.io, monitor your Web applications, measure database performance, optimize SQL queries, explore Functional JavaScript, boost Web server performance in general and optimize applications when there is nothing left to optimize by going beyond performance. After reading this book, you will know how to boost the performance of any Web application and make it part of what has come to be known as the Faster Web.

Client-side caching


Let's continue with another Faster Web technology, which is client-side caching. This form of HTTP caching focuses on reducing the number of requests needed to render a page in order to avoid network latency as much as possible. Indeed, large responses often need many roundtrips over the network. HTTP client-side caching tries to minimize the number of these requests in order to complete the page's rendering. Nowadays, all major browsers offer support for these techniques and enabling these technologies on your website is as easy as sending a few additional headers or using library files that are already available on Content Delivery Networks (CDNs). Let's have a look at these two techniques: browser caching headers and CDNs.

Browser caching

Browser caching is based on the idea that it is not necessary to fetch all the files included in a response if some of these are exactly the same over a certain period of time. The way it works is through headers that are sent by the...
