The following packages are in testing, and available for download in the testing repositories:

• php56w 5.6.4
• php55w 5.5.20
• php54w 5.4.36

EL7 versions of the packages are delayed due to a non backwards-compatible update in Mariadb stopping compilation that is being fixed.

Assuming you have the Webtatic repositories set up (see Yum Repository), you can update using:

    yum update <package> --enablerepo=webtatic-testing
