The /var/www/html folder is the document root folder of your web server. Everything that you save in /var/www/html folder can be accessed via web browser (ex: index.html).

Install PHP 7 on CentOS

Another important part of the lamp stack is PHP. PHP is a scripting language, One of the most widely used technologies for creating dynamic web content.

PHP 7 is the latest version, but not available from the default centos software repository. So will use the epel and webtatic repository which provides PHP 7 for CentOS.

First, enable the epel and webtatic repositories:

rpm -Uvh https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm
rpm -Uvh https://mirror.webtatic.com/yum/el7/webtatic-release.rpm
yum repolist

Next, install php7 and related packages:

yum -y install mod_php71w php71w-cli php71w-common php71w-mysqlnd php71w-mbstring

Then, restart the Apache Server:

systemctl restart httpd.service

To test PHP installation, Create the index.php file in /var/www/html with the following content:

<?php
phpinfo();
?>

After saving the file, type http://server_ip/index.php and You should see the output of PHP's phpinfo() function.
