I am running PHP 5.3.3 on my servers. Why ?

Summary: running newer versions is a lot of effort.

I run CentOS 6 so I run the PHP that is packaged for it. While it might be nice
to have PHP 5.6 it would involve me in a lot of work (compile from source) and I
would need to do that with each new release/patch. As it is I just go 'yum
update' and security fixes, ..., are all installed - easy peasy.

If I were to upgrade to CentOS 7 (a lot of work - but it is what I put on new 
ones) I
would have PHP 5.4.

The RedHat support term is 10 years and will still be in common use until 2020.
I like that - putting a server together can be a lot of work; it can do a lot
more than just run PHP.

If PHP 5.<latest> were available in EPEL[**] I would look to upgrade to a more
modern PHP.  EPEL would make use much easier. It will not happen without someone
putting the work in ... and it is much more than just compiling the tar ball,
there must be patching and testing in the enterprise environment.

[**] A place where other RedHat packages live, sometimes more modern versions of
packages in the base distribution.
