如何在PHP应用程序中使用加载程序脚本？

Question

So I have designed a PHP application that uses an oAuth2 API integration to create a unique interface for a CRM. App is working great on my server, and am ready to offer it to my clients.

My initial idea for expanding this was to create a unique subdomain for each of them on my server, create a new database, and install my application onto that subdomain. My application only has one hard-coded file with the database login details, the rest is stored on a database.

The problem I see with this is it is inefficient. I am essentially going be putting in the same files in many directories, which doesn't make a whole lot of sense. Plus updating it would be annoying.

Since everything is being hosted by me, it was suggested that I create a core folder with all of the files. Then I could use a loader script to read the database settings, and then use relative paths to access the core folder.

My issue is how would this work? Suppose my core domain is https://core.mydomain.com and my customer url is https://cus.mydomain.com . Customer logins through their url. Now a customer wants to access https://cus.mydomain.com/person.php . How would I make that work, considering that file is not located there (since it is in the core folder) ? Would this require using custom htaccess?

If my current idea is wrong, what approach would you suggest? I am not married to this approach, and am looking for an efficient way of updating and managing the app. Thank you!

Use a symbolic link? https://en.wikipedia.org/wiki/Ln_(Unix)

You can create a folder with all your static files in /var/www/core/ and create a symbolic link in each customers folder.

ln -s /var/www/core /var/www/customer001/core/

this way all modifications in /var/www/core/ will be available to all customers
