如何使用Baidu Push擴展，在PHP應用中實現推送統計與裝置管理功能

<?php

use BaiduBaiduPushClient;

$client = new Client($apiKey, $secretKey);

// 获取全量推送统计信息
$response = $client->report->getReport();
if ($response->isSuccess()) {
    $reportList = $response->getResult();
    foreach ($reportList as $report) {
        // 打印推送统计信息
        echo "成功：" . $report['success']
            . "，失败：" . $report['fail']
            . "，配额使用量：" . $report['quota'];
    }
} else {
    // 打印错误信息
    echo "获取推送统计信息失败：" . $response->getErrorMsg();
}

<?php

use BaiduBaiduPushClient;
use BaiduBaiduPushRequestsCreateTagRequest;
use BaiduBaiduPushRequestsQueryTagDevicesRequest;

$client = new Client($apiKey, $secretKey);

// 创建标签
$tag = 'test';
$response = $client->tag->createTag(new CreateTagRequest($tag));
if ($response->isSuccess()) {
    echo "创建标签成功";
} else {
    echo "创建标签失败：" . $response->getErrorMsg();
}

// 查询标签下的设备列表
$response = $client->tag->queryTagDevices(new QueryTagDevicesRequest($tag));
if ($response->isSuccess()) {
    $deviceList = $response->getResult();
    foreach ($deviceList as $device) {
        // 打印设备信息
        echo "设备ID：" . $device['channel_id'];
    }
} else {
    // 打印错误信息
    echo "查询设备列表失败：" . $response->getErrorMsg();
}
