Question

I am on centos 6.5 and when I install do yum install php-common it goes ahead and installs some packages, but php is still not installed. And, when I want to install php directly it is says php-common is causing conflict and does install the php module or even php-cli independently.

What is php-common used for?

As you can so, it basically contains the .so modules for curl, zip, fileinfo, json, and phar, plus license/support files.
