[CentOS 7] How to install PHP on CentOS 7

Michail

Introduction

PHP (Hypertext Preprocessor) is a server-side programming language that was created specifically for web development (websites, web applications and other projects). Its main advantage over other languages is the ability to embed PHP code directly into HTML.

In this tutorial, we will install the PHP 8.3 version. However, you can install a different version by following the given steps.

WARNING

CentOS 7 reached the EOL June 30, 2024:

https://blog.centos.org/2023/04/end-dates-are-coming-for-centos-stream-8-and-centos-linux-7/

Because of this, you may encounter some repository issues. We recommend that you reinstall another OS that has not yet reached EOL.

If you are using CentOS 7 and encounter a mirror issue, please check out this guide to resolve the problem.
