I would quite like to be running the latest production releases of PHP and MySQL on my production RHEL5.3 server.
PHP so that I can use Zend Framework 1.9 which only supports PHP 5.2.4 or later.
MySQL because they claim 5.1 is faster.
I am a little concerned about installing from RPM's because of breaking dependencies and having to manually keep things up-to-date afterwards.
After a bit of research, I found the Remi Repository.
If I add this to my list of repositories, yum update will be able to upgrade PHP and MySQL.
This sounds too good to be true - so are there any pitfalls or problems that I should be aware of?
