As we know that PHP is the most important part of LAMP applications (WordPress, Joomla, Drupal & Media wiki etc). Now a days most of these applications require PHP 7 for their installation and configuration. Main advantage of PHP 7.x is that it will load your web application faster and will consume less server’s resources like CPU and RAM.
PHP is a recursive acronym for PHP: Hypertext Preprocessor. It is server-side scripting. One can write dynamically generated web pages in PHP or embedded PHP directly into HTML. PHP offers built-in database integration for several commercial and non-commercial database management systems. By default, CentOS 7/RHEL 7 comes with PHP version 5.4 only.
