Hi.Wolfe,

I want to send command to our device via stream_socket,but i am confuse to use this,all i want is to send command to device then i want to get the response from the device and write it to a file or log file.

here is my code,and it’s not working…


<?php
$command = "@@A27,013723008965451,D01,0*BB\\r\
";//this is the command i want to send to our device
$file = fopen('mylogs.log','w');
$server = stream_socket_server("tcp://127.0.0.1:1337", $errno, $errorMessage);

if ($server === false) {
    throw new UnexpectedValueException("Could not bind to socket: $errorMessage");
}


for (;;) {
    $socket = @stream_socket_accept($server);
    if ($socket) {
        stream_socket_sendto($socket, $command, STREAM_OOB);
        $dataflag =  stream_socket_recvfrom($socket, 1500, STREAM_OOB);
        stream_copy_to_stream($dataflag, $file);//copy bytess to mylogs.log
        fclose($file);
        fclose($socket);
    }
}


?>

I’m still unsure of what your “device” is. I’m assuming that your “device” already has a socket server present on it? Try to use telnet to establish a connection, and send that command. Once you get some connectivity and response, then let’s come back to this.

From the looks of your code, your trying to turn your localhost (not the remote device) into the socket server.

Your trying to connect IN to the device correct? The ip address of your device is not going to be 127.0.0.1, that’s your localhost.
