话不多说上干活

public function downloadMatchDataAction()
{

    // 要下载的信息
    $user = new UserModel();
    $sql = "SELECT id,name,age,sex ORDER BY age DESC LIMIT 0,100";
    $list = $user->query($sql);//这里可以理解为查出来的二维数组
    $th = ['编号','姓名','年龄','性别'];
    $datas = array();//定义空数组，用来装自己想要的数据格式
    foreach($list as $key => $val){
        $datas[$key][] = $val["id"];
        $datas[$key][] = $val["name"];
        $datas[$key][] = $val["age"];
        $datas[$key][] = $val["sex"];
    }
   //解释一下这个循环，$datas为二维数组，$key为$list的键，将$list里面的键变为$datas里面的键最后再给这个键附上我刚才查询的值
    $this->outCsvTableAction('match',$th,$datas);//这里注意，指的是调用累内该方法
    exit;//我这里我选择了退出因为导出并下载我已经完成了，做完以后还需要做记录请自行修改。
