I use CentOS 5.5 64bits, and I'd strongly prefer running php5.3 there (please focus on this), but if you have a safe recipe to run it on another distribution, I'll take it into consideration.
My problem is that I get to achieve either one of these two things:
I install php5.3 (from here: http://www.webtatic.com/blog/2009/06/php-530-on-centos-5/) and everything works, but without PDO.
I install everything from 'remi' repos (including their own MySQL version, because otherwise I'd get an incompatibility error while installing), but when it comes to the part of the script where I use PDO, I get a blank screen and it dies without leaving any errors (even with errors activated).
Thanks in advance.
