Socket trouble

[René Fournier <m5@xxxxxxxxxxxxxxxx>]

I'm having some trouble with my socket client. I would like it to 
"notice" when the server is no longer there, and then reconnect. I have 
code for the reconnect, etc., but I can't figure out how to write the 
socket_read code so that it "notices" when the server is gone and then 
responds. Presently, my client just hangs (CPU goes to 100%, nothing 
happens.)

Here's my code:

while(($buf = socket_read($socket,1,PHP_BINARY_READ)) !== false) {
				$data .= $buf;
				if(preg_match("/TERMINATING/",$data)) {
					$msg_recv = 1;
					break;
					}
				}

The PHP docs on socket_read suggest how this might be done:

"Note: socket_read() may return a zero length string ("")  indicating 
the end of communication (i.e. the remote end point has closed the 
connection)."

Does this "end of communication" include cases when the socket server 
dies without gracefully disconnecting? How could my code check for this 
zero length string? Any help is much appreciated. Thanks!

...René
