发送多个 iPhone 推送通知 + APNS + PHP [英] Sending multiple iPhone push notifications + APNS + PHP

问题描述

我正在开发一个 PHP 网站 + iPhone 应用程序和用于 iPhone 应用程序的 API，有一个面向学生和医生的消息传递系统，当任何人(从网站或 iPhone)发送消息时，其他用户应该在他的 iphone 上收到推送通知.例如，如果学生为老师添加了一个新问题，老师 iPhone/iPad 上的推送通知将发送给老师，当老师回复学生的答案时，学生将收到推送通知.

I am working on a PHP website + iPhone application and API for iPhone application, has a messaging system for students and doctors, when any one sends message (from website or iPhone) the other user should get push notification on his iphone. For example if student adds a new question for teacher, a push notification on teachers iPhone/iPad will be send to teacher and when teacher replies to student's answer, student will get a push notification.

由于没有老师和学生注册网站的数量限制，我的问题是如何向注册用户的iPhone发送推送消息?我想在有人回复或添加问题后立即发送推送消息.请向我提供用于发送多条推送消息的 PHP 代码.我在注册时为每个用户保存设备令牌.

Since there is no restriction on number of teachers and student registering to website, my question is how to send push messages to registered user's iPhone? I want to send push message as soon as someone replies or adds a question. Please provide me PHP code for sending multiple push messages. I am saving device token for each user while registration.

当老师回复问题时，我正在给学生发送邮件，我也想向学生发送推送通知，反之亦然，因此请指定能够管理错误情况的代码.

When teacher reply to question I am sending mail to student, I want to send a push notification too to student and vice versa so please specify code able to manage error conditions.

1. 已下载apns-php
2. PHP 代码

    set_time_limit(0);
    $root_path = "add your root path here"; 
    require_once($root_path."webroot\cron\library\config.php");

        $timezone = new DateTimeZone('America/New_York');
        $date = new DateTime();
        $date->setTimezone($timezone);
        $time =  $date->format('H:i:s');


        //Get notifications data to send push notifications
        $queueQuery = " SELECT `notifications`.*, `messages`.`mes_message`, `messages`.`user_id`, `messages`.`mes_originated_from`  FROM `notifications`
