Glad to see this article, as I've also been of the opinion lately that as developer's, we need to be trying to push PHP hosting forward as well.

Aside from writing code for a specific PHP version that still has support, we can also not let clients use hosts that are on old versions of PHP. Sometimes we don't like to be too pushy about this, but really it's for the client's own benefit, and if you do more than casually mention it, they'll often listen.

Great looking project on Github, Coen, I'll definitely be taking a look at using it on my next project.
