3. Code Implementation

The following is a code example of using PHP to implement the website map function of the CMS system:

<?php
// 遍历整个网站目录，查找所有PHP文件
function traverseWebsite($dir){
    $fileArr = array();
    $handle = opendir($dir);
    if ($handle){
        while (($file = readdir($handle)) !== false){

                continue;
            }elseif (is_file("$dir/$file") && pathinfo($file, PATHINFO_EXTENSION) == 'php'){
                $fileArr[] = "$dir/$file";
            }elseif (is_dir("$dir/$file")){
                $fileArr = array_merge($fileArr, traverseWebsite("$dir/$file"));
            }
        }
        closedir($handle);
    }
    return $fileArr;

    $url = $matches[1];
    
    $pageInfo['url'] = $url;
    $pageInfo['title'] = $title;

// 生成网站地图
function generateSitemap($dir){
    $pages = traverseWebsite($dir);
    
    $sitemapContent = '<ul>';
    foreach ($pages as $page){
        $pageInfo = getPageInfo($page);
        $sitemapContent .= '<li><a href="'.$pageInfo['url'].'">'.$pageInfo['title'].'</a></li>';
    }
    $sitemapContent .= '</ul>';

    // 保存网站地图为静态HTML文件
    file_put_contents('sitemap.html', $sitemapContent);
    
    return 'sitemap.html';

// 使用示例
$websiteDir = '你的网站根目录路径';
$sitemapResult = generateSitemap($websiteDir);
echo '网站地图生成成功！<a href="'.$sitemapResult.'">点击查看</a>';
?>
