I followed this tutorial to update PHP from 5.3 version to 5.4. My distro is CentOS 5.5. after running following command:

yum --enablerepo=remi,remi-test install httpd php php-common  

I get following error:

  --> Missing Dependency: php-common = 5.3.13-1.w5 is needed by package php-zts-5.3.13-1.w5.i386 (installed)
Error: Missing Dependency: php-common = 5.3.13-1.w5 is needed by package php-zts-5.3.13-1.w5.i386 (installed)
Error: php53-common conflicts with php-common
 You could try using --skip-broken to work around the problem
 You could try running: package-cleanup --problems
                        package-cleanup --dupes
                        rpm -Va --nofiles --nodigest
The program package-cleanup is found in the yum-utils package.

How can I solve this error?
