PHP 7 support

I can't make this work on PHP 7.2. Any luck somebody? Or I might create a docker file just for this :)

Ah wont work. It complains about the return value declarations of function as syntax error.

Oh it actually works on PHP7.2. Generates proper output, just throws an error at the end. Didn't notice fist that the output file contained a proper doc. cool
