socket functions

[Anon]

I had posted a query about fsockopen last week and have since discovered the function pfsockopen. This function should keep a socket connection open for multiple writes. However, I am still not able to get this to work. Can anyone provide some help? Below is my test code.

<?php

$socket = pfsockopen("host.domain.com", 80, $errno, $errstr); $sld = array ('refgasdcv', 'test222', 'test333', 'test444', 'test555', 'Frida y666', 'Saturday777');

$a=0; while ($a < 10000) { $sld="sld[$a]";
socket_set_blocking($socket, false) ; //set blocking to false $poststring2="command=purchase&tld=com&sld=$sld&responsetype=tex t&pw=riay&uid=j1";
$in = "GET /interface.asp?" . $poststring2 . " HTTP/1.1\r\n\r\n";
$in .= "connection: keep- alive\n\n";
var_dump(socket_get_status ($socket));
$write=Fputs( $socket, $in, strlen( $in ) );
$res = fread($socket, 2000); // Read response

echo "ERROR $errno - $errstr";
echo $a;
$a++;
}
fclose( $socket ); // Close the socket ?>

I don't know if this helps, but I just wrote a program (with help from the community here) to get the status, players and rules off of a half-life server using sockets.

What I ended up doing is that whenever I wanted to write something to the server, I would socket_set_blocking($fp, 1), then I would read back a little, and if I was expecting a lot of reads, I would socket_set_blocking($fp,0) during the read, and then set it back to 1 before the write.

Thanks for your reply.. So, do you think it's necessary to use blocking during writes? Or could I just leave out blocking all together?

Thanks again

From what I've read in the posts about reading alot from the device is that it appears to 'lock up' after about 80-150 bytes read. I don't know if this is just a case with the half-life server, or if its a function of php, so to answer your question, in my case, I needed it.
