Hello,
I have a small but somewhat annoying issue.
Whenever I open a socket to another server, the file is read very
quickly, but it takes the up to 30 seconds or so to close the connection...
Here is what I do:
$sever = "server.mit.edu";
$url = "/link";
$port = 80;
$user_agent = $_SERVER['HTTP_USER_AGENT'];
$server_protocol = $_SERVER['SERVER_PROTOCOL'];
$valsencoded = "";
while (list($key,$value) = each ($content))
$valsencoded .= urlencode($key) . "=" . urlencode($value) ."&";
$valsencoded = substr($urlencoded,0,-1);
$content_length = strlen($valsencoded);
$headers = "POST $url $server_protocol
Content-Type: application/x-www-form-urlencoded
Host: $server
Content-Length: $content_length
";
// open socket
$socket = fsockopen($server, $port, $errno, $errstr, 60.0);
if (!$socket) {
$error = "ERROR: cannot contact Mailman server";
return array(false,$error,$error); }
if ($errstr) {
$error = "ERROR: fSockOpen Error ($errno): $errstr";
return array(false,$error,$error); }
fputs($socket, $headers); // send headers
fputs($socket, $urlencoded); // send post data
// "tried stream_set_timeout($socket,3)" here
// get the returned page
while (!feof($socket))
{
$buf = @fgets($socket, 2048);
$htmlreturned .= $buf;
}
fclose($socket);
If I put a debug 'echo "BUF: $buf\n" inside the while loop, I see the
returned html from the post show up pretty much immediately, within
about a second, maybe less.
However, the process 'stalls' after that for between 15-30 seconds, and
then ends correctly.
I have tried to use timeouts, but they did not have any effects (did not
really expect them to, but just in case).
My setup is Debian 4.0, php 5.2.0-8+etch7. Unfortunately I don't know
the other server OS's/applications.
I found similar questions in posts from 2002 and 2003, but there were no
replies (2002-04-30 guido.d.berger and 2003-11-25 thomas weber).
Any ideas greatly appreciated,
Alvar
