thinkphp的数据库操作,使用链式写法。

文件路径:tp/application/index/controller/Test.php

访问其中的方法时,使用 tp.top/index.php/index/test/update,查看执行的结果

实例

<?php
namespace app\index\controller;
use think\Db;

class Test
{
    public function find(){
        $res = Db::table('staf')
            ->field('name,sex,salary')
            ->where('staff_id',2)
            ->find();
        dump($res);
    }

    public function select()
    {
        $res=Db::table('staf')
            ->field('name,sex,salary')
            ->where('salary','>',3000)
            ->order('salary','DESC')
            ->limit(5)
            ->select();
        dump($res);
    }

    public function insert()
    {
        $data=[
            'name'=>'halc',
            'sex'=>1,

        $num=Db::table('staf')->data($data)->insert();
