}

// 查询分享量最高的文章
$sql = "SELECT a.article_id, a.title, COUNT(*) as total FROM article_share AS s
        LEFT JOIN article AS a ON s.article_id = a.article_id

// 统计不同渠道的用户转化率
$sql = "SELECT channel, COUNT(*) as total FROM subscribe
        GROUP BY channel";

// 统计不同推广活动的点击量和转化率

// 统计不同推广活动的ROI
$sql = "SELECT campaign, SUM(revenue) as total_revenue, SUM(cost) as total_cost FROM campaign_stats
        GROUP BY campaign";
