入口文件index.php/控制器/方法
index.php/index/Data/conn

namespace app\index\controller;
use think\Db;

class Data
{
    public function conn()
    {
        return Db::table('tp_auth_group')
        ->where('id',2)
        ->value('title');

    }
    }
    ?>

浏览器表输出测试数据
管理员

此表那个字段都输出数据失败，不明白，
public根目录下/indexdata.php
/indexdata.php
直接调用数据表测试

//$con = mysql_connect("localhost","root","password");
$con = mysql_connect("localhost","root","root");
$select_db = mysql_select_db('tp51smcms');

if (!$select_db) {

    die("could not connect to the db:\n" .  mysql_error());

}

//查询代码

//$sql = "select * from db_table";
$sql = "select * from tp_member";
$res = mysql_query($sql);

if (!$res) {

    die("could get the res:\n" . mysql_error());

}

while ($row = mysql_fetch_assoc($res)) {

    print_r($row);

}

//查询代码

//关闭数据库连接

mysql_close($con);

?>

浏览器输出
