Kindly elaborate on "neverending GET request". Shall I call the script from
within itself?

You can do it without polling. I've seen web applications that open a
neverending GET request in order to get updates to the browser
instantaneously.

I refer to having the javascript code open a GET request that never ends
and streaming data from the server back to the client. The server-side
PHP process, which stays running, streams back data whenever it becomes
available. This of course uses a lot of memory. I have never done this
myself in a web application, so I suggest you google for examples of
other people who have actually implemented it.
