//模型公众方法，递归
public function treeLevel(array $data, int $pid = 0, string $html = '--', int $level = 0)

//静态数组不在方法内，所以无法覆盖
static $arr = [];
foreach ($data as $val) {

$val['level'] = $level + 1;
//如果是0，则是*菜单

//递归处理层
public function sonLevel($data, $pid = 0)

$arr = [];
foreach ($data as $val){
if ($val['pid'] == $pid){
$val['son'] = $this->sonLevel($data,$val['id']);
