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.

The infrastructure


We discussed too many topics on increasing the performance of our application. Now, let's discuss the scalability and availability of our application. With time, the traffic on our application can increase to thousands of users at a time. If our application runs on a single server, the performance will be hugely effected. Also, it is not a good idea to keep the application running at a single point because in case this server goes down, our complete application will be down.

To make our application more scalable and better in availability, we can use an infrastructure setup in which we can host our application on multiple servers. Also, we can host different parts of the application on different servers. To better understand, take a look at the following diagram:

This is a very basic design for the infrastructure. Let's talk about its different parts and what operations will be performed by each part and server.
