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?

Please try with CVS HEAD and report back.

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 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.

No.

I'm closing this as this is your client which has the habbit to send every single character on its own over the line.

As php.net/socket_select states: "If you read/write to a socket returns in the arrays be aware that they do not necessarily read/write the full amount of data you have requested. Be prepared to even only be able to read/write a single byte."

And, I tried the same thing you did, also with clients from a linux system which only sent the data after I entered return. Just be prepared to received single characters.
