PHP无法与Apple通知网关进行套接字连接

免责声明：在SO上我发现了许多类似的问题和一些答案,但没有一个解决了我的问题.

我有这个简单的PHP代码：

<?PHP
    $deviCEToken = "myDeviCEToken";
    $message = "Hello from server";
    $badge = 1;
    $sound = "default";

    // Construct the notification payload
    $bodY['aps'] = array(
        'alert' => $message
    );

    if ($badgE) {
        $bodY['aps']['badge'] = $badge;
    }

    if ($sound) {
        $bodY['aps']['sound'] = $sound;
    }

    /* End of Configurable Items */
    $ctx = stream_context_create();
    stream_context_set_option($ctx,'ssl','local_cert','my.pem');

    $fp = stream_socket_client("ssl://gateway.sandBox.push.apple.com:2195",$err,$errstr,60,STREAM_CLIENT_CONNECT,$ctX);

    if (!$fp) {
        print "Failed to connect $err $errstrn";
        return;
    } else {
        print "Connection OK\n";
    }

    $payload = json_encode($body);
    $msg = chr(0) . pack("n",32) . pack("H*",str_replace(" ","",$deviCEToken)) . pack("n",strlen($payload)) . $payload;
    print "sending message :" . $payload . "\n";
    fwrite($fp,$msg);
    fclose($fp);
?>

知道发生了什么事吗？
