Minor point of style: We tend to refer to phpng in lowercase, because that's the branch name. Although at this point, since it no longer exists as a branch (it's long since been merged into trunk) and there have been subsequent performance optimisations, the names "PHP 7" or "Zend Engine III" are possibly better.
