帮助PHP脚本列出目录需要递归

function listFilesRecursive($dir) {
    $result = array();
    $files = scandir($dir);
    
    foreach ($files as $file) {
        if ($file === '.' || $file === '..') {
            continue;
        }
        
        $path = $dir . '/' . $file;
        
        if (is_file($path)) {
            $result[] = $path;
        } elseif (is_dir($path)) {
            $result = array_merge($result, listFilesRecursive($path));
        }
    }
    
    return $result;
}

$directory = '/path/to/directory';
$files = listFilesRecursive($directory);

foreach ($files as $file) {
    echo $file . "\n";
}
