admin2年前Laravel689

public function bottom($mid = 3)
{
   $members = DB::select('select id,parent_id,`level` from member where status= 1  and parent_id >= 0');
   $Teams = array();//最终结果
   $mids = array($mid);//第一次执行时候的用户id
   do {
       $othermids = array();
       $state = false;
       foreach ($mids as $valueone) {
           foreach ($members as $key => $valuetwo) {
               if ($valuetwo->parent_id == $valueone) {
                   $Teams[] = $valuetwo->id;//找到我的下级立即添加到最终结果中
                   $othermids[] = $valuetwo->id;//将我的下级id保存起来用来下轮循环他的下级
                   $state = true;
               }
           }
       }
       $mids = $othermids;//foreach中找到的我的下级集合,用来下次循环
   } while ($state == true);
   array_push($Teams, $mid);
   return $Teams;
}
