ThinkPHP無限分類

Question

根據id,pid怎麼進行無限分類

#

Answer 1

使用遞歸函數，不過我寫這種方法空間複雜度沒有優化，忘記以前的寫法了

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

用遞歸來循環出一個陣列
