thinkphp5.1模型对象返回对象的形式，转成数组只需要修改database.php中的配置：'resultset_type' => 'array',array修改为：collection即可。

object(think\model\Collection)#42 (1) {
  ["items":protected]=>
  array(1) {
    [0]=>
    object(app\index\model\Admin)#40 (2) {
      ["data"]=>
      array(18) {
        ["id"]=>
        int(1)
        ["is_admin"]=>
        int(1)
        ["username"]=>
        string(5) "admin"
        ["fullname"]=>
        string(13) "administrator"
        ["phone"]=>
        string(11) "15887288437"
        ["password_reset_token"]=>
        string(32) "98641e30ace18a76f07bd7e5fbf7cd6c"
        ["access_token"]=>
        string(32) "43641e30ace18a74207b27e3f3f3d6ff"
        ["email"]=>
        string(12) "admin@qq.com"
        ["password"]=>
        string(32) "98641e30ace18a76f07bd7e5fbf7cd6c"
        ["login_times"]=>
        int(5)
        ["login_ip"]=>
        string(9) "127.0.0.1"
        ["login_time"]=>
        int(1608477052)
        ["last_login_ip"]=>
        string(9) "127.0.0.1"
        ["last_login_time"]=>
        int(1608477052)
        ["user_agent"]=>
        string(0) ""
        ["create_time"]=>
        int(1608477052)
        ["update_time"]=>
        int(1608477052)
        ["status"]=>
        int(1)
      }
      ["relation"]=>
      array(0) {
      }
    }
  }
}

可能你修改了查询出来的记录还是对象形式，所以还需在select()后追加->toArray()，比如：select()->toArray();

var_dump((new Admin())->select()->toArray());

array(1) {
  [0]=>
  array(18) {
    ["id"]=>
    int(1)
    ["is_admin"]=>
    int(1)
    ["username"]=>
    string(5) "admin"
    ["fullname"]=>
    string(13) "administrator"
    ["phone"]=>
    string(11) "15887288437"
    ["password_reset_token"]=>
    string(32) "98641e30ace18a76f07bd7e5fbf7cd6c"
    ["access_token"]=>
    string(32) "43641e30ace18a74207b27e3f3f3d6ff"
    ["email"]=>
    string(12) "admin@qq.com"
    ["password"]=>
    string(32) "98641e30ace18a76f07bd7e5fbf7cd6c"
    ["login_times"]=>
    int(5)
    ["login_ip"]=>
    string(9) "127.0.0.1"
    ["login_time"]=>
    int(1608477052)
    ["last_login_ip"]=>
    string(9) "127.0.0.1"
    ["last_login_time"]=>
    int(1608477052)
    ["user_agent"]=>
    string(0) ""
    ["create_time"]=>
    int(1608477052)
    ["update_time"]=>
    int(1608477052)
    ["status"]=>
    int(1)
  }
}

如果不修改resultset_type的配置为：collection，而是resultset_type=>"array"的情况，在使用：

// table方法必须指定完整的数据表名
$result = Db::table('tp5_admin')->select();
var_dump($result);

返回的即为数组形式：

array(1) {
  [0]=>
  array(18) {
    ["id"]=>
    int(1)
    ["is_admin"]=>
    int(1)
    ["username"]=>
    string(5) "admin"
    ["fullname"]=>
    string(13) "administrator"
    ["phone"]=>
    string(11) "15887288437"
    ["password_reset_token"]=>
    string(32) "98641e30ace18a76f07bd7e5fbf7cd6c"
    ["access_token"]=>
    string(32) "43641e30ace18a74207b27e3f3f3d6ff"
    ["email"]=>
    string(12) "admin@qq.com"
    ["password"]=>
    string(32) "98641e30ace18a76f07bd7e5fbf7cd6c"
    ["login_times"]=>
    int(5)
    ["login_ip"]=>
    string(9) "127.0.0.1"
    ["login_time"]=>
    int(1608477052)
    ["last_login_ip"]=>
    string(9) "127.0.0.1"
    ["last_login_time"]=>
    int(1608477052)
    ["user_agent"]=>
    string(0) ""
    ["create_time"]=>
    int(1608477052)
    ["update_time"]=>
    int(1608477052)
    ["status"]=>
    int(1)
  }
}

进过测试，如果'resultset_type' => 'collection',的情况下，Db类返回的就是对象形式，要返回array形式，也许要在select()后使用->toArray();的形式。

// table方法必须指定完整的数据表名
$result = Db::table('tp5_admin')->select();
var_dump($result);

object(think\Collection)#39 (1) {
  ["items":protected]=>
  array(1) {
    [0]=>
    array(18) {
      ["id"]=>
      int(1)
      ["is_admin"]=>
      int(1)
      ["username"]=>
      string(5) "admin"
      ["fullname"]=>
      string(13) "administrator"
      ["phone"]=>
      string(11) "15887288437"
      ["password_reset_token"]=>
      string(32) "98641e30ace18a76f07bd7e5fbf7cd6c"
      ["access_token"]=>
      string(32) "43641e30ace18a74207b27e3f3f3d6ff"
      ["email"]=>
      string(12) "admin@qq.com"
      ["password"]=>
      string(32) "98641e30ace18a76f07bd7e5fbf7cd6c"
      ["login_times"]=>
      int(5)
      ["login_ip"]=>
      string(9) "127.0.0.1"
      ["login_time"]=>
      int(1608477052)
      ["last_login_ip"]=>
      string(9) "127.0.0.1"
      ["last_login_time"]=>
      int(1608477052)
      ["user_agent"]=>
      string(0) ""
      ["create_time"]=>
      int(1608477052)
      ["update_time"]=>
      int(1608477052)
      ["status"]=>
      int(1)
    }
  }
}

此时在select()后添加：->toArray();如下：

array(1) {
  [0]=>
  array(18) {
    ["id"]=>
    int(1)
    ["is_admin"]=>
    int(1)
    ["username"]=>
    string(5) "admin"
    ["fullname"]=>
    string(13) "administrator"
    ["phone"]=>
    string(11) "15887288437"
    ["password_reset_token"]=>
    string(32) "98641e30ace18a76f07bd7e5fbf7cd6c"
    ["access_token"]=>
    string(32) "43641e30ace18a74207b27e3f3f3d6ff"
    ["email"]=>
    string(12) "admin@qq.com"
    ["password"]=>
    string(32) "98641e30ace18a76f07bd7e5fbf7cd6c"
    ["login_times"]=>
    int(5)
    ["login_ip"]=>
    string(9) "127.0.0.1"
    ["login_time"]=>
    int(1608477052)
    ["last_login_ip"]=>
    string(9) "127.0.0.1"
    ["last_login_time"]=>
    int(1608477052)
    ["user_agent"]=>
    string(0) ""
    ["create_time"]=>
    int(1608477052)
    ["update_time"]=>
    int(1608477052)
    ["status"]=>
    int(1)
  }
}
