How to use PHP to log in to the system with multiple accounts from the same browser at the same time

Question

Multiple users with different roles log in to the same backend on the same browser. How can the session not be overwritten? Users with different roles can be identified and the operations of each user can interfere with each other. Currently, we know that QQ mailbox adds sid as the user's identifier in the URL. , but it is not realistic to add all URLs one by one. I don’t know how QQ mailbox does it, that is, all operations must bring SID. Is there a better way to achieve it? Please help me, please help me.
