Learning PHP 7 High Performance

Overview of this book

PHP is a great language for building web applications. It is essentially a server-side scripting language that is also used for general-purpose programming. PHP 7 is the latest version, providing major backward-compatibility breaks and focusing on high performance and speed. This fast-paced introduction to PHP 7 will improve your productivity and coding skills. The concepts covered will allow you, as a PHP programmer, to improve the performance standards of your applications. We will introduce you to the new features in PHP 7 and then will run through the concepts of object-oriented programming (OOP) in PHP 7. Next, we will shed some light on how to improve your PHP 7 applications' performance and database performance. Through this book, you will be able to improve the performance of your programs using the various benchmarking tools discussed. At the end, the book discusses some best practices in PHP programming to help you improve the quality of your code.

Load testing real-world applications

We studied three tools in this chapter to load test. Now, it is time to load test some real-world applications. In this section, we will test Magento 2, Drupal 8, and WordPress 4. All these open source tools will have their default data.

We have three VPS configured with NGINX as the web server. One VPS has PHP 5.5-FPM, the second has PHP 5.6-FPM, and the third has PHP 7-FPM installed. The hardware specs for all the three VPS are same, and all applications we will test will have the same data and the same versions.

This way, we will benchmark these applications with PHP 5.5, PHP 5.6, and PHP 7 and take a look at how fast these applications can run on different versions of PHP.

Note

In this topic, we won't cover configuring the servers with NGINX, PHP, and the databases. We will assume that the VPS are configured and that Magento 2, Drupal 8, and WordPress 4 are installed on them.

Magento 2

Magento 2 is installed on all VPS, and all the caches are enabled for...
