<?php
// 假设你已经加载了 phpcms 的框架和数据库连接
$catid = $_GET['catid']; // 获取当前页面的栏目ID

// 查询当前栏目的父栏目ID
$sql = "SELECT parentid FROM v9_category WHERE catid = $catid";
$result = $db->query($sql);
$row = $db->fetch_array($result);

// 如果父栏目ID为0，表示当前栏目是顶级栏目
if ($row['parentid'] == 0) {
    // 查询顶级栏目的名称
    $sql_top_category = "SELECT catname FROM v9_category WHERE catid = $catid";
    $result_top_category = $db->query($sql_top_category);
    $row_top_category = $db->fetch_array($result_top_category);
    echo "当前顶级栏目名称：" . $row_top_category['catname'];
