APNS+PHP - 超过 200 个令牌无法传递消息

Question

我可以向 APNS 发送关于我数据库中大约前 200 个设备令牌的通知，但在这些消息之后消息失败，这是我的本地服务器日志的一部分，其中发生了伤害：

我可以验证消息开始失败的设备令牌 #239 是有效令牌，因为我向其发送了一条消息并且消息已成功送达。

在我的远程服务器中，我得到了一个更详细的错误日志，它是：

Warning: fwrite(): SSL: Broken pipe in

on line 51
Processing #33: d77c5cb283646ed5f480....

我发送通知的循环代码：

.....above:The connection and preparing of payload
// Encode the payload as JSON
$payload = json_encode($body);

$i = 0;
//Send the Push to each token the close connection
foreach ($deviceTokens as $deviceToken) {
    // 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));

    echo 'Processing #'.$i.': '.$deviceToken.'<br>';
    $i++;
    if (!$result) {
        echo 'Message not delivered <br>' . PHP_EOL;
            //usleep(400000); //400 msec
        }
    else {
        echo 'Message successfully delivered <br>' . PHP_EOL;
        }
}


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

....End of function

非常感谢任何帮助。

根据@Nick 回答的正确代码

//Move the connection to a separated function
//to reconnect again easily in case of failing
$fp = connectToAPNS($directory, $passphrase);

$i = 0; //Logging counter

//Send the Push to each token the close connection
foreach ($deviceTokens as $deviceToken) {
        // Build the binary notification
        $msg = chr(0) . pack('n', 32) . pack('H*', $deviceToken) . pack('n', strlen($payload)) . $payload;

        for ($k = 0 ; $k < 2 ;$k++) { //Number of tries in case of connection interruption
            // Send it to the server
            $result = fwrite($fp, $msg, strlen($msg));

            echo 'Processing #'.$i.': '.$deviceToken.'<br>';
            $i++;
            if (!$result) {
                echo 'Message not delivered at k='.$k.'<br>' . PHP_EOL;
                fclose($fp);
                $fp = connectToAPNS($directory, $passphrase);
            }
            else {
                echo 'Message successfully delivered at k='.$k.'<br>' . PHP_EOL;
                break; //Stop trying 
            }
        }

    }


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

我的日志现在是：

与 APNS 服务器的连接可能因多种原因而被切断。当写入由于这些原因中的任何一个而失败时，您必须重新打开连接。您可以尝试再次将消息发送到同一令牌，但请记住，如果它确实是无效令牌，连接将不断中断。

在您的循环中，当写入失败时，您无需重新打开与 APNS 的连接就可以继续下一个令牌；这是行不通的。添加一些代码以在失败时重新打开连接。您甚至可以添加一些代码来找出写入失败的原因，以确定您是否应该重试当前令牌。您也可以阅读我的回答 here 以获取一些提示。
