PHP develops push notifications and vibration prompts for real-time chat function

In modern social network applications, real-time chat function has become an indispensable part. In order to provide a better user experience, developers often need to send live chat messages to users in the form of push notifications and alert them through the device's vibration function when new messages are received. This article will introduce how to use PHP to develop push notifications and vibration prompts for real-time chat functions.

The implementation of push notifications needs to rely on a message push service, such as Firebase Cloud Messaging (FCM) or Apple Push Notification Service (APNS). First, we need to register a developer account and obtain the corresponding API key or certificate. Then, depending on the selected push service, we can use the corresponding PHP library to send push notifications.

The following is a sample code for sending push notifications using Firebase Cloud Messaging:

<?php

// 设置Firebase Cloud Messaging API密钥
define('FIREBASE_API_KEY', 'YOUR_API_KEY');

function sendPushNotification($to, $title, $body, $data = []) {
    $message = [
        'to' => $to,
        'notification' => [
            'title' => $title,
            'body' => $body,
        ],
        'data' => $data,
    ];

    $headers = [
        'Authorization: key=' . FIREBASE_API_KEY,
        'Content-Type: application/json',
    ];

    $ch = curl_init();
    curl_setopt($ch, CURLOPT_URL, 'https://fcm.googleapis.com/fcm/send');
    curl_setopt($ch, CURLOPT_POST, true);
    curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
    curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
    curl_setopt($ch, CURLOPT_POSTFIELDS, json_encode($message));
    $result = curl_exec($ch);
    curl_close($ch);

    return json_decode($result, true);
}

// 使用示例
$to = 'DEVICE_TOKEN';
$title = '新消息';
$body = '您有一条新的聊天消息';
$data = [
    'chat_id' => 'CHAT_ID',
    'sender_id' => 'SENDER_ID',
];

$result = sendPushNotification($to, $title, $body, $data);
print_r($result);

In the above code, we need to replace YOUR_API_KEY with your own Firebase Cloud Messaging API Key, DEVICE_TOKEN is replaced with the token of the target device. $title and $body are used to define the title and body of the push notification, $data is an optional additional data that can be used in the application further processing.

The implementation of vibration prompts mainly relies on the Vibration API of HTML5. This API allows us to control the vibration function of the device programmatically. The following is a sample code that uses JavaScript to implement vibration prompts:

// 使设备震动
function vibrate(duration) {
    if ('vibrate' in navigator) {
        navigator.vibrate(duration);
    }
}

// 使用示例
vibrate(200); // 200毫秒的震动

The duration parameter in the above code represents the duration of the vibration, in milliseconds. By calling the navigator.vibrate() function, we can trigger the device's vibration function.

Combining push notifications and vibration prompts, we can remind users through push notifications when they receive new chat messages, and trigger the vibration function of the device at the same time to enhance the user experience.

To sum up, this article introduces how to use PHP to develop push notifications and vibration prompts for real-time chat functions. By using the corresponding push service and JavaScript API, we can effectively send live chat messages to users and provide vibration reminders. The addition of these features will significantly improve the interactivity and user experience of the application.
