The following works for me:
$fp = fsockopen("localhost", 25);
stream_set_blocking($fp, false);
fwrite($fp, "QUIT\r\n");
while(!feof($fp)) {
$data = fgets($fp);
var_dump($data);
}
echo "\nAll done\n";
Under Win2000, WinXP, Linux2.4.19 (with IPv6), FreeBSD4.5 (with
IPv6)...
Not verified at all for me.

Remember that feof() will only return true when there is no more data
in the internal buffer held by the stream, so you need to drain off any
input by consuming it all first.

The nature of non-blocking sockets means that your script must always
be prepared to handle a false or zero length return from fgets/fread,
so I'm not worried about that aspect.
However, the feof() does seem to be a problem.
Looking into it...

I've noticed that I need the sleep() in order to retrieve the data.
The behaviour with blocking/non blocking sockets haven't changed
though, its still the same in php 4.3.0 as it were in previous php
versions.
What has changed is the feof() that never return true.

It seems that socket_set_blocking($fp,FALSE); results in other peculiar
behaviour.
When connecting to SMTP server, the server sends some data across the
socket right away, usually something identifying the server.
$fp = fsockopen("mail_server", 25);
var_dump(fgets($fp, 1024));
fclose($fp);
returns the server identify string
$fp = fsockopen("mail_server", 25);
socket_set_blocking($fp,FALSE);
var_dump(fgets($fp, 1024));
fclose($fp);
returns (false)
$fp = fsockopen("mail_server", 25);
sleep(1);
socket_set_blocking($fp,FALSE);
var_dump(fgets($fp, 1024));
fclose($fp);
returns identify string.
The position of the sleep() call can be after socket_set_blocking() as
well.
