确认Tp5连接数据库
<?php
namespace app\index\controller;
use think\Controller;
use think\Db;
class Index extends Controller
{
public function index()
{
$res =Db::connect();
dump($res);
}
}

出现相关信息,连接成功。
tp5 阅读了增加
use think\Controller;
use \think\Request;
use think\Db;
use think\Loader;
public function ceshi(){
$name='小兰';
$data=Db::name('ce')->where('name',$name)->field('click_num')->select();
$click_num=$data[0]['click_num']; //12
$click_nums=$click_num+1;
$data=Db::name('ce')->where('name',$name)->setField('click_num',"$click_nums");
//dump($data);die;
if($data ===1){
return 'true';
}else{
return 'false';
}
}
也可以用TP5 自带的自增+1 方法
$datas =Db::name('tonghua')->where('id', $id)->setInc('click_num'); //点击率加1
// score 字段加 1
Db::table('think_user')->where('id', 1)->setInc('score');
// score 字段加 5
Db::table('think_user')->where('id', 1)->setInc('score', 5);
// score 字段减 1
Db::table('think_user')->where('id', 1)->setDec('score');
// score 字段减 5
Db::table('think_user')->where('id', 1)->setDec('score', 5);
TP5 简单的过滤设置
tp5 二表关联查询
tp5 去除index.php 修改.htaccess
<IfModule mod_rewrite.c>
Options +FollowSymlinks -Multiviews
RewriteEngine on
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^(.*)$ index.php [L,E=PATH_INFO:$1]
</IfModule>
