Can't install php-mysql module

First time using php 5.5 and well I'm getting a lot of headaches.

I can't install php-mysql, I get the following error:

Error: Package: php-mysql-5.4.30-1.el6.remi.x86_64 (remi)
       Requires: php-pdo(x86-64) = 5.4.30-1.el6.remi

You could try using --skip-broken to work around the problem
You could try running: rpm -Va --nofiles --nodigest

What do I do?

You forgot to enable the remi-php55 repository from which you intended to get the packages.

You should make this persistent by editing the repo configuration file /etc/yum.repos.d/remi.repo and ensuring that the remi and remi-php55 repos are enabled.
