The HTTP protocol works on the request-response principle which means that the server can only generate a response following a request from the client. This means that the server cannot send a response to the client without having received a request in the first place. This is not a PHP issue, it is an HTTP issue. So no, you can't push, the client has to make a request, or poll. You could take a look at long polling, as alex suggested.
