I can&#x27;t defend any code quality (and I&#x27;m certainly not associated with the project, I merely host my own&#x2F;private network)...but i suppose php was chosen as the stack for (hopefully) more universal adoption.  Most low-cost&#x2F;budget (old school) web hosting companies support php out of the box...and the intent is for folks to host their own network instead of hopping on others, etc.
