增加数据
<?php
namespace Home\Controller;
use Think\Controller;
class IndexController extends Controller {
public function add(){
$db = D("Info");
//1.使用数组方式
$arr =
array("Code"=>"p005","Name"=>"妈拉巴子"
,"Sex"=>1,"Nation"=>"n003","Birthday"=>"1999-02-03");
$db->add($arr);
//2.使用映射的方式
$db->Code = "P006";
$db->Name = "你妹";
$db->Sex = 1;
$db->Nation = "C004";
$db->Birthday = "1996-03-04";
$db->add();
}
}
