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.

Summary

In this chapter, we discussed different tools to debug a PHP application. We used Xdebug, Sublime Text 3, and Eclipse to debug our applications. Then, we used the Xdebug profiler to profile an application to find out the execution statistics. Finally, we discussed PHP DebugBar to debug an application.

In the next chapter, we will discuss load testing tools, which we can use to place load or virtual visitors on our application in order to load test it, and find out how much load our application can bear, and how it affects the performance.
