Chapter 1. Setting Up the Environment

PHP 7 has finally been released. For a long time, the PHP community was talking about it and has still not stopped. The main improvement in PHP 7 is its performance. For a long time, the PHP community faced performance issues in large-scale applications. Even some small applications with high traffic faced performance issues. Server resources were increased, but it did not help much because in the end the bottleneck was PHP itself. Different caching techniques were used, such as APC, and this helped a little. However, the community still needed a version of PHP that could boost the application's performance at its peak. And this is where PHPNG comes in.

PHPNG stands for PHP next generation. It is a completely separate branch and is mainly targeted for performance. Some people thought that PHPNG is JIT (Just In Time) compilation, but in reality, PHPNG is based on a refactored Zend Engine, which was highly optimized for performance. PHPNG is used as a base for PHP 7 development, and according to the official PHP wiki page, the PHPNG branch is now merged into the master branch.

Before starting to build an application, the development environment should be finalized and configured. In this chapter, we will discuss setting up the development environment on different systems, such as Windows and different flavors of Linux.

We will cover the following topics:

All other environments can be skipped, and we can set up the environment that we will use.
