Question

根据id,pid怎么进行无限分类

Answer 1

使用递归函数，不过我写这种方法空间复杂度没有得到优化，忘记以前的写法了

private function getTreeList($data, $pid = 0)
    {
        $resultarr = array();
        foreach ($data as $teamdata) {
            if ($teamdata['pid'] == $pid) {
                $team_data = $teamdata;
                $children_data = $this->getTreeList($data, $teamdata['id']);
                $team_data['children'] = $children_data;
                $resultarr[] = $team_data;
            }
        }
        return $resultarr;
    }

Answer 2

用递归来循环出一个数组
