Does upgrading OpenAudit also upgrade PHP and if so what version of PHP does OpenAudit 2.0.11 upgrade to?
no, upgrading open-audit does not upgrade php.
if you have no php installed when running the open-audit installer, then the installer will use apt or yum to install whatever php version your linux distribution provides.
