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.

Service-oriented architecture (SOA)


In service-oriented architecture, the application's components provide services to each other on a defined protocol. Each component is loosely coupled with each other, and the only way of communication between them is through the services they provide.

In PHP, Symfony provides the best way to have SOA as it is mainly an HTTP-centric framework. Symfony is the most mature, well-tested collection of libraries that are widely used by other PHP frameworks, such as Zend Framework, Yii, Laravel, and others.

Let's consider a scenario where we have a backend and a frontend for a website and a mobile application. Normally, in most applications, the backend and frontend run on the same code base and on a single access point, and an API or web service is built for mobile applications to communicate with this backend. It is good, but we need great. So, for high performance and scalable applications, the separate components run independently of each other. If they need...
