I've found fsockopen to be very reliable. I've done a few socket scripts
with PHP (WhoisPro, et al).
I believe the easiest way to check for a remotely closed socket is to do an
fgets() and check for EOF:
while (!feof($connection)) {
$buffer .= fgets($connection, 4096); // 4096 is the chunk size, you can
adjust it
}
I *think* EOF on a socket deonotes a remote socket close but I could be
horribly wrong.
