Ios PHP推送通知服务，反馈为空

推送工作正常，问题是反馈是空的。我需要删除已过期或状态无效的令牌。 这是我的推送代码：

// Push code example
$ctx = stream_context_create();
stream_context_set_option($ctx, 'ssl', 'local_cert', $certificateName);
//stream_context_set_option($ctx, 'ssl', 'verify_peer', false);
//stream_context_set_option($ctx, 'ssl', 'passphrase', $passphrase);

// Open a connection to the APNS server
$fp = stream_socket_client('ssl://gateway.sandbox.push.apple.com:2195', $err,$errstr, 60, STREAM_CLIENT_CONNECT|STREAM_CLIENT_PERSISTENT, $ctx);

if (!$fp) {
    exit("Failed to connect: $err $errstr" . PHP_EOL);
}

// Create the payload body
$body['aps'] = array(
    'alert' => $message,
    'sound' => 'default'
);

// Encode the payload as JSON
$payload = json_encode($body);

// Build the binary notification
$msg = chr(0) . pack('n', 32) . pack('H*', $deviceToken) . pack('n', strlen($payload)) . $payload;

// Send it to the server
$result = fwrite($fp, $msg, strlen($msg));

if (!$result) {
    echo '<p>The message has not been sent '. PHP_EOL;
} else {
    echo '<p>The message has been sent  ' . PHP_EOL;
}

// Close the connection to the server
fclose($fp);

结果是空的

二,。 //设置默认时区 日期默认时区设置（“欧洲/布加勒斯特”）

结果也是空的。。。。请提供帮助。

苹果沙盒反馈服务器似乎不返回非活动令牌，尽管生产环境似乎工作正常。
看看这条线：

建议的解决方案是在您的设备上安装两个开发应用程序，然后删除一个。已删除的令牌应显示在非活动令牌列表中。

这也是我注意到的。过了一段时间，它就开始工作了。。。奇怪的苹果。谢谢这也是我注意到的。过了一段时间，它就开始工作了。。。奇怪的苹果。非常感谢。
