Answer 1

Mysql中有一个group_concat函数，你可以试试看。
大致的sql语句如下：

SELECT term_id, group_concat(village_name) as area FROM tb_name GROUP BY term_id;

Answer 2

$data=array();
        foreach(数据库数组 as  $v){
            if(!isset($data[$v['team_id']])){
                $data[$v['team_id']]=$v['village_name'];
            }else{
                $data[$v['team_id']].=','.$v['village_name'];
            }
        }
        $d=array();
        foreach($data as $kk=>$vv){
            $d[]=array(
                'team_id'=>$kk,
                'area'=>$vv,
            );
        }
        unset($data);
        var_dump($d);
