How to properly organize work with a font-end developer?

Question

Yii

There was a need to connect a remote front-end developer to the project on which I am working, the project is written in php (yii framework). The question is how can I give him access to the client part so that he cannot see and edit the server part, including not having access to the database?
PHP itself is used as a template engine, so what's the point of sharing only the folder with views, if necessary, you can pull everything from there and connect to the database.

Answer 1

If you still do not have a dev server and a test database with test data, it's time to create them. And such restrictions greatly spoil life and development in the most unexpected moments.

Answer 2

Of course, this is expensive, but still ...
You can replace real models with mock objects. A freelancer will not have a database or logic, and mock objects will come in handy when testing

Answer 3

Thanks for answers. I have another question, but what if you use a template engine and provide access to these templates, will this solve the problem? As far as I understand, it is impossible to execute arbitrary php code from it, but only manipulate the data that I output, will this approach be more useful or harmful?
