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.

HTTP server optimization


Each HTTP server provides certain features that can be used to optimize request handling and serving content. In this section, we will share some techniques for both Apache and NGINX that can be used to optimize the web server and provide the best performance and scalability. Mostly, when these optimizations are applied, a restart for Apache or NGINX is required.

Caching static files

Mostly, static files, such as images, .css, .js, and fonts don't change frequently. So, it is best practice to cache these static files on the end user machine. For this purpose, the web server adds special headers to the response, which tells the user browser to cache the static content for a certain amount of time. The following is the configuration code for both Apache and NGINX.

Apache

Let's have a look at the Apache configuration to cache the following static content:

<FilesMatch "\.(ico|jpg|jpeg|png|gif|css|js|woff)$">
  Header set Cache-Control "max-age=604800, public
</FileMatch...
