I'm trying to set up Symfony2 on a Centos 6.3 server.
It mostly works, but there are several warnings relating to the version of PHP that is on the server (5.3.3).
In summary, the warnings suggest that PHP version should be 5.3.8 or later, and also earlier than 5.3.16.
I just can't work out how to upgrade PHP to these versions. Can anyone help me please?
