The socket functions listed on that page should work to open, close,
listen for, and send data across TCP sockets? 

Here's what the developer is trying to do:
$length = strlen($output);
$hexlength = dechex($length);
$hexlength1 = "\x95";
$header = "\x02\x46\x44\x02\x00$hexlength1";
$footer = "\x03\x46\x44\x03";
$header .= "$output$footer";
$output = "$header";


$host = "ww.xx.yy.zz";
$port = XXXXX;

//Open a client connection
$fp = fsockopen($host, $port, $errno, $errstr);

if (!$fp){
$result = "Error: Could not open socket connection";
}else{
//Write the user string to the socket
fputs ($fp, $output, strlen($output));
//get the result
while(!eof($fp))
{
$result .= fgets($fp, 1024);
}
//close the connection
fclose($fp);
}

I guess the fput function works and data gets sent, but when the
response is sent it hangs. In a way, it's like the code doesn't
recognize an "EOF"....
Like I said, I'm not a developer so any help or pointers would be
appreciated!

Thanks.
