New Comment:
i ran your script and connected with teraterm pro from my win2000 box
(local):
i typed 'hello world' ans then disconnected.
this is the output i got:
D:\Apache\htdocs>d:\php\php-cli -q -f d:\apache\htdocs\testje.php
string(1) "h"
string(1) "e"
string(1) "l"
string(1) "l"
string(1) "o"
string(1) " "
string(1) "w"
string(1) "o"
string(1) "r"
string(1) "l"
string(1) "d"
"ring(2) "
i guess this should have been a single line, right?
i couldn't test it at this moment with a connection from my linux box
since i'm in a NAT'ed network.
i will try later though.

How did you test sending data to your php script which received the
data? I've noticed that the telnet version shipped with windows does by
default transmit every character immidiately over the line (hence
resulting only in single characters sent). If I telnet from a linux
host to the script running under win32 I recevied the whole data only
after I pressed return.
I've tested it with this simple script:
<?
error_reporting(E_ALL);
if (false === ($s = socket_create(AF_INET, SOCK_STREAM, SOL_TCP)))
exit;
if (false === socket_bind($s, '0.0.0.0', 8765))
exit;
if (false === socket_listen($s, 10))
exit;
if (false === ($t = socket_accept($s)))
exit;
while ($data = socket_read($t, 1024)) {
var_dump($data);
}
?>

i have exactly the same problem with win2000.
it closes the connection immidiatly after the first received char.
that little scriptlet upthere seems to be be a way around this.
is this a bug or is it suppost to work like this?

In the documentation, it's written that socket_read() reads data from
the socket until a \n, \t, \0.... or until the end of the buffer.
But under win32 it reads only 1 char.
This would be fixed.
Just use instead :
$buf="";
while (substr($buf,-1)!="\n") {
$buf.=socket_read($socket,1);
}
I've put 1 here, but you can write 16777216 it'll continue to give back
only 1 char.
