Import php

What I’m wondering is I have script that wasn’t created by blocs can I import the .php pages to edit them I really just want to make them look better. and blocs would make it easier because I could see visual what was happening.

Blocs isn’t able to edit existing html and php pages. And it also doesn’t want to do that.

Regarding your other questions I don’t think Blocs is the right application for your use cases.
