Rather than banging my head, I think I shall ask the experts first.
From a web page, using javascript, there is no way to talk and listen to a
daemon on linux ( I gathered from folks here).
1. Using javascript I can send data to a PHP file and wait for it reply (aka
AJAX).
2. Assume that the PHP file is on the same server running the daemon.
Question
---------
Can I do this:
I send my data to a PHP file via XmlHttpRequest; the PHP file communicates
with the daemon and get its reply, after which the PHP will return the
result to my javascript ?
Thanks folks (forgive me if it is stupid).

To people who know nothing, anything is possible.
To people who know too much, it is a sad fact
that they know how little is really possible -
and how hard it is to achieve it.

How is the PHP script going to communicate with the daemon?
Why are you beating your head against the wall trying to reinvent the wheel?

Websocket?
Too early to advice that.
http://en.wikipedia.org/wiki/Web_socket#Browser_support
Maybe in a few years, but now is too early.
He can better implement the XHR approach if he wants it to work today. :-)

Using socket in PHP, localhost, port number which the daemon is listening.
Not possible on a web server ?

Just cross my mind whether this is a possibility. Possibly a poor man's
option.

Too early to advise that? Perhaps. But its as well to be aware of it.
Recent browsers all support it, whether they support the recently
completed RFC exactly is another matter.
