Tutorial: Use the JPush push extension to add scheduled message push and message postback functions to PHP applications

1. Introduction
JPush is a powerful push service platform that can help developers implement message push Function. In PHP applications, we can use the JPush push extension to add scheduled message push and message postback functions. This article will detail how to use the JPush push extension to achieve these two functions.

2. Configure JPush push extension

1. Download JPush push extension
   First, we need to download the JPush push extension. We can download the latest JPush push extension from the JPush official website (https://www.jpush.cn/).
2. Install JPush push extension
   Unzip the downloaded JPush push extension, copy the extension folder to the extension directory of the PHP application, and add the extension configuration in the PHP configuration file.
3. Configuring JPush push
   Register an account on the JPush official website and create an application, and obtain necessary information such as AppKey and MasterSecret. In the configuration file of the PHP application, configure JPush push-related information, such as AppKey and MasterSecret.

3. Scheduled message push
In PHP applications, we can use the scheduled message push function of the JPush push extension to implement scheduled message push.

1. Create a scheduled task
   In order to push messages regularly, we need to create a scheduled task first. We can use PHP's scheduled task tool to perform scheduled tasks, such as Crontab on Linux systems.

The following is an example of a scheduled task script that can be added to Crontab:

* * * * * php /path/to/your/php/file.php

2. Write PHP code
   In the PHP script for scheduled task execution , we need to write the code to push the message. Using the API provided by the JPush push extension, we can easily implement the function of regularly pushing messages.

The following is an example PHP code for implementing scheduled push messages:

require_once '/path/to/your/jpush/library/JPush.php';
use JPushClient as JPushClient;

$jpush = new JPushClient($appKey, $masterSecret);
$message = ['title' => '定时消息', 'content' => '这是一条定时推送的消息'];
$pushPayload = $jpush->push()
    ->setPlatform('all')
    ->addAllAudience()
    ->message($message)
    ->build();
$response = $pushPayload->send();

In the above code, we first instantiate JPushClient and pass in the AppKey and MasterSecret. Then, we define the content of the message to be pushed. Finally, we use the API provided by the JPush push extension to set the push platform, push target and message content, and send the push message.

4. Message postback function
In PHP applications, we can use the message postback function of the JPush push extension to obtain the postback results of push messages.

1. Writing PHP code
   Using the API provided by the JPush push extension, we can easily obtain the return results of the push message.

The following is an example PHP code for obtaining the return result of a push message:

require_once '/path/to/your/jpush/library/JPush.php';
use JPushClient as JPushClient;

$jpush = new JPushClient($appKey, $masterSecret);
$messageId = '消息的唯一标识';
$result = $jpush->report()->getReceived($messageId);

if ($result['isOk']) {
    $receivedList = $result['received_list'];
    foreach ($receivedList as $item) {
        // 处理回传结果
    }
}

In the above code, we first instantiate JPushClient and pass in the AppKey and MasterSecret. Then, we define the unique identifier of the message to be returned. Finally, we use the API provided by the JPush push extension to obtain the return results of the push message and process the return results.

5. Summary
Through the introduction of this article, we can learn how to use the JPush push extension to add scheduled message push and message postback functions to PHP applications. Using the JPush push extension, we can easily implement the message push function and improve the user experience of the application. Hope this article is helpful to you!

Please note that the above sample code is only for demonstration and needs to be modified and optimized according to specific needs in actual applications.
