# wget http://rpms.famillecollet.com/enterprise/remi.repo

Step 2: Install/Upgrade PHP to version 7.0

Firstly remove the older php installation using yum remove command as shown below:

# yum remove php php-cgi php-cli php-common

Stop the Apache2 service

# service httpd stop

# yum --enablerepo=remi-php70 install php
