foreach循环赋值问题

foreach ($list as $key=>$val){
    $data=array();//这一个一定要加上不然循环后，modify_one,modify_two都会赋值
    if ($val['id']!=1){
        $link = explode("801",$val['p_link']);
        if (isset($link['1'])){
            if ($val['times']%2==0){
                $data['modify_two']=$ftp->time($link['1']);
            }else{
                $data['modify_one']=$ftp->time($link['1']);
            }
            $admin->edit_modify($val['id'],$data);
            $admin->addTimes($val['id']);
        }
    }
}
