  4. Request example:{"request":"status-get","addr":"395:14","API-KEY":"08283242722612433"}

function api_send($sock, $req) {
    $r = '-JSON-'.$req;
    return fwrite($sock, pack('I', strlen($r)) . $r);

function api_recv($sock) {
    $s = fread($sock, 4);
    $size = unpack("I", $s)[1];
    $data = fread($sock, $size);
    if (strpos($data, '"error"')) {

    $key = $req['API-KEY'];
    $post = json_encode($req);
} else $key = $headers['API-KEY'];

$sock = stream_socket_client('unix:///tmp/sh.socket', $errno, $errst);
$auth_req = '{"request": "authorize","key": "'.$key.'"}';
api_send($sock, $auth_req);
api_send($sock, $post);
echo api_recv($sock);
