Of course you have the memory overhead of the PHP interpreter's RAM

Let me explain my project more in detail.
This system is an Instant messaging system, with the backed
running on apache / php / mysql. The front end client is a COM
component that communicates with the backend, and interfaces with
an MFC app.
Now since Instan
You're right- this is getting interesting ;)

Unless I'm mistaken, you don't need to actually hijack the socket- you merely
need to write to the network. Check out section 3.1 of RFC 793. There is
source and destination port- that is how

True, the listen-fork model would hardly be any lines of code, but
the changes that will have to be done to the client and the server
would be enormous. We are talking abt a production system here

Why not just keep your script running and have it send more data

Thanks for the reply Miguel, but here i'm not trying to implement
my own multi-threaded server - exactly the reason why i'm using
Apache / PHP.
I could have made a listening server which is based on a
multi-threaded or multi-forked model, but the time and
complexities involved would be huge.
Ah, yes - http://php.net/pcntl_fork
Well there you go, then - everything required to create a server in PHP.

I don't think you're going to get Apache to hand you the socket.
However, you can write a program using the standalone (CGI) PHP
interpreter that will act like a server - check out
http://php.net/socket_create_listen for more info.
You could redirect from your standard web server to your liste
Vinod,
Interesting...
Okay unless I'm mistaken, what you want to do can't be accomplished through
PHP. However, you may want to take a look at libnet.

It still seems like I havent made the problem clear enough.
I am aware of the print(), echo() and flush() functions and what
they do. It does not fit in as a solution. Let me explain my

Tx for your very prompt reply.
Yeah, I'll post the solution as soon as I find it someplace.
Let me outline the problem in more detail -

connection type as Keep-Alive. The PHP script, somehow (still a
big question) gets the so
