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
With Red Hat and derived distributions, I recommend using the remi repository to get PHP packages (and symfony) to ensure a stable system (though with necessary bugfix updates as well). It currently contains PHP 5.3.19, symfony 1.4.20 and symfony2 2.1.3.
