The packages referenced in the document are all PHP 7.0. Is this the minimum required version or can I go with the version provided in the CentOS default repositories and/or EPEL. I’m reluctant to add additional repositories that may not have the levels of validation that those repositories have.
I’m unable to find any specifics on required minimums and the only versions mentioned seem to be on that document.
5.4 at present is supported for v1 but please please please just don’t. 7 is highly recommended due to the performance gains. However you should go for at least 5.6 seeing as that’s the minimum supported version by PHP itself.
5.6 is the min for v2 which is currently in early alpha stage.
