Installing PHP 7.x on Centos 7

To install php 7.x we need to install a few things first

sudo yum -y install epel-release

sudo yum -y install http://rpms.remirepo.net/enterprise/remi-release-7.rpm

sudo yum -y install yum-utils

Now enable the version of php 7 you wish you install
sudo yum-config-manager –enable remi-php72

Note: if you want to install php 7.0 or 7.1 you can use the command below.
yum-config-manager –enable remi-php70
yum-config-manager –enable remi-php71
You see 72 stands for 7.2, 70 stands for version 7.0 and 71 stands for 7.1

Finally its time to installinstall PHP 7.2
sudo yum -y install php

Add (MySQL/MariaDB) database support to php
sudo yum -y install php-mysqlnd

Don’t forget to restart the server after php installation for the changes to take effect.
sudo service httpd restart
or
sudo systemctl restart httpd.service

Congrats you have now successfully install PHP 7.x in your server.

To check php version
