If you could do this directly, then the network would be really unsafe.

include can include remote files, but the code of the remote config.php file cannot be obtained because it will be parsed. You can only get the content output after parsing. Then you might as well directly pull the remote json file with curl, and then parse it to get the value.

You can
use readfile() better

What a dangerous idea. Use the API idea

Are you afraid that it will be inconvenient for others to criticize you? It's too dangerous. Use a solution like API or RPC.

It depends on whether the remote server can parse PHP. If not, the remote server will access the original content of the file. If it can, the parsed html content will be returned.

It is not safe to include remote files. It is recommended to use API
