How to solve package conflict in Centos 6

Question

I am trying to upgrade from php 5.5 to 5.6, so far i've managed to upgrade to php5.6, setup suPHP 0.7, and add php-mysql extension. I used the webtatic repo to install php 5.6 I read on this page that it is not advised to have webtatic along remi. So i removed the files in /etc/yum.conf.d/ in order to not have webtatic in the list of repo.

However I couldn't install the php-xml for DomDocument, some CMS use it.

I tried :

yum install php-xml

not working

yum --enablerepo remi install php-xml

It gives me the message :

Résolution des dépendances

Vous pouvez essayer d'utiliser --skip-broken pour contourner le problème
 Vous pouvez essayer d'exécuter : rpm -Va --nofiles --nodigest

I tried the --skip-broken parameter but i receive:

--> Lancement de la transaction de test

Paquets omis en raison de problèmes de dépendances :
php-common-5.5.38-7.el6.remi.x86_64 depuis remi-php55
php-pecl-jsonc-1.3.10-2.el6.remi.5.5.x86_64 depuis remi-php55
php-xml-5.5.38-7.el6.remi.x86_64 depuis remi-php55

Then I tried rpm -Va --nofiles --nodigest, and then again the previous command, but still can't solve the problem. Thank you for any help !

UPDATE: I manage to get the owner of the remi repository https://rpms.remirepo.net/wizard/, there is a configurator, I chose the version of php, and it laid out the steps to achieve what you want, but unfortunately i had this message :

Erreur du contrôle de transaction :

I am trying to solve this issue now in their forum.

Disclaimer: I am having a little trouble with the language barrier, but I think enough of it makes sense along with your description in English.

I think you need to remove the packages that were installed with webtatic, not just remove the repo. Specifically, it looks like php56w-common is from that repo and is the source of your trouble. You'll want to install PHP 5.6 from remi-php56 and stick to one 3rd party ecosystem.
