Here are updated packages in the Yum repository:
Note PHP.net has EOL'd (End of Life) PHP 5.3, however this Webtatic release contains the latest security fixes since then. Currently I'm still deciding on how to proceed with either supporting PHP 5.3 for longer, or making it EOL. Maintaining it requires additional effort which I'd be interested in seeing if you would consider paying a subscription for.
