How to Install PHP 7 on CentOS ?

Before proceeding with the installation steps and procedure, you need to ensure that the user have sudo privileges enabled to be able to install packages.

1. Configure Yum Repository

To begin, you have to install and enable EPEL and Remi yum repository on your CentOS 7 server. Run the below commands to install and enable EPEL and Remi yum repository:

$ sudo yum install https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm
$ sudo yum install http://rpms.remirepo.net/enterprise/remi-release-7.rpm

Now we are going to install yum-utils. It is a collection of useful programs for managing yum repositories and packages. It has tools that improve yum's default features.

$ sudo yum install yum-utils

Next, we will use yum-config-manager program which is included in yum-utils. We will use it to enable Remi repository as the default repository for installing different PHP versions.

Now you can install the stable version of PHP on your server.

Run the following commands to install PHP 7 on CentOS 7 server.

First choose specific php version of your choice and enable appropriate Remi repository for install PHP 7 as below:

For PHP 7.4
$ yum --enablerepo=remi-php74 install php
For PHP 7.3
$ sudo yum-config-manager --enable remi-php73
For PHP 7.2
$ sudo yum-config-manager --enable remi-php72
For PHP 7.1
$ sudo yum-config-manager --enable remi-php71

After that, install PHP 7 with additional necessary modules which can extend the core functionality. Run below command:

$ sudo yum install php php-mcrypt php-cli php-gd php-curl php-mysql php-ldap php-zip php-fileinfo

Now, PHP is installed with specific version. 

Afterwards, you can check the installed PHP version.

2. Install PHP Modules

You may also need to install additional PHP modules based on your application requirements. Below command will install some more useful PHP modules:

## Install PHP 7.4 ##

## Install PHP 7.1 ##

You can run the following command to search other available PHP modules under configured yum repositories. 

Below example command search for all modules for PHP 7.4.

3. Verify PHP Installation

You can check installed PHP version using command line by type:

 Zend Engine v3.3.1, Copyright (c) 1998-2018 Zend Technologies
     with Zend OPcache v7.3.1, Copyright (c) 1999-2018, by Zend Technologies

Next, you can test your system to know if it is configured properly for PHP, create a very basic PHP script called info.php file.

So create this file at web root of server.

In CentOS 7 directory is located at /var/www/html/ so create file here by executing this command :

$ sudo nano /var/www/html/info.php

Add the following PHP code inside the file:
