mORMot Open Source

I'm wanting to generate websites that use core functionality provided by the api.

Hello, looking at this again now. Ready to proceed with projects and still not sure about this technology. Refining the question above:

By using the mormot code I will be able to create REST API's that handle various components of my program - calculators, database actions - and then install the exe on the private hosted php server. Web pages (mainly via php/jquery) can then call the api?

I am getting a little confused with how this fits in with having to publish compiled php extensions which I think I can do with Delphi and would also want to do. Thus, can the mormot application be able to communicate with such extensions, or do they need to just be compiled in to the exe. My concern then is what happens when multiple users are accessing at the same time.

I have also been looking at Phalcon but I have a lot of Delphi back end code I'd like to get access to online.

Thank you. Sorry, I am just getting back into programming after a long break and having trouble wrapping my head around this. Mormot is such a big project that it would be disastrous to find out after several months of learning it that it was the wrong platform.
