[PHP知识库]PHP数据递归展示

建议写在Base模型中

 //递归展示
    public function treeLevel(array $data,int $pid = 0,string $html = '--',int $level = 0){
        static $arr = [];
        foreach($data as $v){
            if($pid == $v['pid']){
                $v['html'] = str_repeat($html,$level * 2);
                $v['level'] = $level+1;
                $arr[] = $v;
                $this->treeLevel($data,$v['id'],$html,$v['level']);
            }
        }
        return $arr;
    }

其他模型中直接查出数据后调用即可
