I am in complete disagreement with Coleman that this is off-topic and should be shoved out to the General Unix and Linux StackExchange. As I seem to be unable to communicate with Coleman through StackExchange, I am reposting this question.
CentOS has their listed repo's at: https://wiki.centos.org/AdditionalResources/Repositories I'd prefer not to get unnecessarily toasted over generally available information.
As one can see, there are many different ones. However, what are the dev's using? What's being tested against? CentOS 6 is still a supported product, yet CiviCRM 4.7 pushes the PHP recommendations past what is default PHP install is for any CentOS/RHEL/Scientific packaging. CentOS 7.2, the newest general release is paired with the PHP 5.4 branch, yet the recommended PHP for CiviCRM is the 5.6 branch.
This is CiviCRM specific. What are the dev's expecting when I install CiviCRM? I can choose a million different ways to install PHP, but only a few of them may work as expected.
Is there any kind of "official" repo for upgrading PHP beyond the stock PHP 5.3.3 found in CentOS 6.7? I'm trying to utilize the SCL repo's, but finding all sorts of peculiarities that seem to point back to this dual PHP install method.
