Web Sites and Unique Peer Identification [PHP]

Question

I am new to websockets. Ive just completed my first multi-purpose socket server, which serves 3 types of messages on the same socket. This server is intended for use as follows:

chat messages

real time market data

user specific alerts

The first two functions work fine, and I'm completely happy, however, I experience a complete loss when it comes to identifying and linking peers in connection with specific accounts, so that I can serve pending alert notifications for specific users.

basically, I save the warnings in a database table as follows:

Table: uc_notifications

account(varchar50) | message(varchar255) | id(primary,AI) | seen(default 0)

I want to keep peers in a table like this:

uc_notification_peers
account(varchar50) | peer_id(unique,varchar100) | id(primary,AI)
