PHP开发实时聊天功能的推送通知与震动提示

<?php

define('FIREBASE_API_KEY', 'YOUR_API_KEY');

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

    $result = curl_exec($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);

// 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
