TP5 列出記錄集

方法一:

  1.引入use think\Db;

 2.查詢資料語句:$rs=Db::name('school')->select();列出所有資料

例子:

<?php
namespace app\admin\controller;
use think\Controller;
use think\Validate;
use think\Request;
use think\Db;
class Main extends controller
{
    public function index()
    {
        return $this -> fetch();
    }
//學校清單
    public function school()
    {
        //$rs=db('school')->select();
        $rs=Db::name('school')->select();
        dump($rs);die;
        return $this -> fetch();
    }      

方法二:助手函數

直接使用查詢語句$rs=db('school')->select();

例子:

<?php
namespace app\admin\controller;
use think\Controller;
use think\Validate;
use think\Request;
//use think\Db;
class Main extends controller
{
    public function index()
    {
        return $this -> fetch();
    }
//學校清單
    public function school()
    {
        $rs=db('school')->select();
        //$rs=Db::name('school')->select();
        dump($rs);die;
        return $this -> fetch();
    }
