That is *not* possible.
PHP genarates the code, sends it to the Client and FINISH.
So you have to do something on the website.
Maybe an AJAX request every x Seconds.
But when the client has no JS, or disabled it....
.... it doesn´t work too.
And when JS is working an the person at the computer is sleeping?


Result:
Forget it.
