我有两台设备在GCM注册。但是，当测试从服务器发送消息时，它只将消息发送到最新注册的设备，而不是所有注册的设备

如何将其更改为发送到这些设备ID：

<?php
    //generic php function to send GCM push notification
   function sendPushNotificationToGCM($registatoin_ids, $message) {
        //Google cloud messaging GCM-API url
        $url = 'https://android.googleapis.com/gcm/send';
        $fields = array(
            'registration_ids' => $registatoin_ids,
            'data' => $message,
        );
        // Google Cloud Messaging GCM API Key
        define("GOOGLE_API_KEY", "(API KEY)"); // My API Key form Google console
        $headers = array(
            'Authorization: key=' . GOOGLE_API_KEY,
            'Content-Type: application/json'
        );
        $ch = curl_init();
        curl_setopt($ch, CURLOPT_URL, $url);
        curl_setopt($ch, CURLOPT_POST, true);
        curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
        curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
        curl_setopt ($ch, CURLOPT_SSL_VERIFYHOST, 0);   
        curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
        curl_setopt($ch, CURLOPT_POSTFIELDS, json_encode($fields));
        $result = curl_exec($ch);               
        if ($result === FALSE) {
            die('Curl failed: ' . curl_error($ch));
        }
        curl_close($ch);
        return $result;
    }
?>
<?php

    //this block is to post message to GCM on-click
    $pushStatus = "";   
    if(!empty($_GET["push"])) { 
        $gcmRegID  = file_get_contents("GCMRegId.txt");
        $pushMessage = $_POST["message"];   
        if (isset($gcmRegID) && isset($pushMessage)) {      
            $gcmRegIds = array($gcmRegID);
            $message = array("message" => $pushMessage);    
            $pushStatus = sendPushNotificationToGCM($gcmRegIds, $message);
        }       
    }

    //this block is to receive the GCM regId from external (mobile apps)
    if(!empty($_GET["shareRegId"])) {
        $gcmRegID  = $_POST["regId"]; 
        file_put_contents("GCMRegId.txt",$gcmRegID);
        echo "Ok!";
        exit;
    }   
?>

检查正在存储的新设备ID是否未清除原始内容。即，添加新设备id时的文件操作应为追加模式。这可能会导致仅发送到最新设备的问题。

您有什么问题-如何存储多个设备ID或如何向它们发送通知？sendPushNotificationToGCM函数似乎可以正确处理此问题。使用deviceID消息向API发出请求。您需要自己存储设备ID。否则为什么这个问题会有php代码来存储deviceid？存储deviceid不是GOOGLE提供的API。Api将发送通知。所以我的回答是确保新条目不会擦除原始数据是有效的。
