I am trying to install PHP MVC framework Symfony. When I go to the check requirements page it says that I have to update my php to version 5.3.17+.
I have an VPS with RedHat. I am totally new in this so I hoped people here could help me with the commands how to upgrade it to php 5.3.17+ or 5.4 (which I prefer).
PHP needs to have PDO working
