What software do you use on server? I need the exact PHP and MySQL

We use Centos 7 or Windows 2008, PHP 5.2/5.3/5.4/5.5/5.6/7.0/7.1/7.2 for basic shared hosting plans. On shared hosting servers 5.5 MySQL database is installed.

You can select OS and other configs according to your project on VPS and Dedicated servers. Also, you can install the desired PHP and MySQL version
