这是我第一次在我的应用程序中使用推送通知。我已经浏览了示例应用程序和书籍，并且了解了如何将推送通知发送到单个设备。但是我没有确切地知道我应该在我的程序中进行哪些更改以将推送通知发送到多个设备。我正在使用“PushMeBaby”应用程序进行服务器端编码。 请帮帮我。

【讨论】：
我发现你必须为每个 fwrite 创建一个新的 stream_context_create 以防止苹果关闭连接以获得错误的令牌。
【讨论】：
fread($socket)：如果它返回FALSE，则重新创建套接字。您还可以将您的发送放入 try&catch 并自动重新创建套接字并重新发送通知（可能有最大重试次数，以防万一）。
尝试此示例代码并根据您的环境进行修改。
$apnsHost = '<APNS host>';
$apnsPort = <port num>;
$apnsCert = '<cert>';
$streamContext = stream_context_create();
stream_context_set_option($streamContext, 'ssl', 'local_cert', $apnsCert);
$apns = stream_socket_client('ssl://' . $apnsHost . ':' . $apnsPort, $error, $errorString, 60, STREAM_CLIENT_CONNECT, $streamContext);
$payload['aps'] = array('alert' => 'some notification', 'badge' => 0, 'sound' => 'none');
$payload = json_encode($payload);
// Note: $device_tokens_array has list of 5 devices' tokens
for($i=0; $i<5; $i++)
{
$apnsMessage = chr(0) . chr(0) . chr(32) . pack('H*', str_replace(' ', '', $device_tokens_array[i])) . chr(0) . chr(strlen($payload)) . $payload;
fwrite($apns, $apnsMessage);
}?>
