Where can I download (view the code) an application made by a professional?

Question

PHP

Hello
Can you advise where you can download some project (online store for example) made by a professional
I would like to look at the file structure and preferably the presence of MVC on this site (suddenly someone else does not use it or other types of file structuring)
And I also want to know your opinion about structuring files, which is better, etc. (I usually used MVC, but I think there are better and more convenient options)

Answer 1
