How To Install PHP 7 on CentOS 7

Install PHP 7 on CentOS 7

In this tutorial, we will show you how to install and configuration PHP 7 on your CentOS 7 server. For those of you who didn’t know, PHP (PHP: Hypertext Preprocessor) is a server-side scripting language designed for web development but also used as a general-purpose programming language. PHP code is interpreted by a web server with a PHP processor module, which generates the resulting web page: PHP commands can be embedded directly into an HTML source document rather than calling an external file to process data. PHP 7 comes with numerous new and improved features. One of the most noticeable is the new Zend Engine version. Also, other important improvements are enhanced performance and significantly reduced memory usage. Thus, PHP 7 can be up to twice as fast as PHP 5.6.

This article assumes you have at least basic knowledge of Linux, know how to use the shell, and most importantly, you host your site on your own VPS. The installation is quite simple. I will show you through the step by step installation of PHP 7 in the CentOS 7 server.
