packages excluded due to repository priority protections

packages excluded due to repository priority protections

I am not able to update my PHP in centos 6.
I have centos base, epel and rpmforge repos.
yum update phpError: Package: php-tidy-5.3.3-14.el6_3.x86_64 (@updates)
Requires: php-common = 5.3.3-14.el6_3
Removing: php-common-5.3.3-14.el6_3.x86_64 (@updates)
php-common = 5.3.3-14.el6_3
Updated By: php-common-5.3.3-23.el6_4.x86_64 (updates)
php-common = 5.3.3-23.el6_4
Available: php-common-5.3.3-22.el6.x86_64 (base)
php-common = 5.3.3-22.el6
You could try using --skip-broken to work around the problem
You could try running: rpm -Va --nofiles --nodigest
.. install failed!
I believe php-tidy has been excluded due to repo priority. How do it fix it?
