Use variabile $_global on remote server

Question

I want to include the variabile $_GLOBAL on many websites which are not hosted in the same place. Or include the file that contains some functions in different sites on different servers.

Everything is done remotely.

I do't want the file to kept on the servers where websites are kept, are 150 websites.

Sorry for my bad english.

Answer 1

If you want to host a data, use database.

If you want to host some remote functions, create a server and create an API so that you can call all the functions remotely. Don't forget some authentication like a secret used in social apps.
