php - One code, many websites -

I need to develop a project that gives me an example of several copies of a website, but each copy is different The website is required. I can upload the same code to many different accounts, but I have to like only one copy of the code. Each website will be an "example", so to speak This way, I can upload the code once and I can update all the websites at the same time.

For technical reasons, I need to use PHP (but I'm also interested in other options for my own knowledge), and I thought the Jellics frame could be a good option. Are there better options?

You can put all the code in one directory, and then you can create a virtual subdirectory for all your In websites, which point to this directory. This way Microsoft resolves the problem in SharePoint.
