文件夹目录的遍历同样也利用递归去一层一层的遍历文件
以下面这个目录为例的

function ($dir, $onlyDir = true)
{
$result = array();
$handle = opendir($dir);
if ($handle) {
while (($file = readdir($handle)) !== false) {
if ($file != '.' && $file != '..') {
$cur_path = $dir . DIRECTORY_SEPARATOR . $file;
if (is_dir($cur_path)) {
$result[$file] = dirList($cur_path, $onlyDir);
} else {
if (!$onlyDir) {
$result[] = $file;
}
}
}
}
closedir($handle);
}
return $result;
}

运行dirList('/web/mall/Application/lib', false)
打印数组
