如果使用了多应用模式，可以快速生成一个应用，例如生成demo应用的指令如下：php think build demo

跨域

Route::group( function () {    Route::get('user', 'user/index');    Route::post('useradd', 'user/useradd');    Route::delete('userdel', 'user/userdel');})->allowCrossDomain([    'Access-Control-Allow-Origin'        => 'http://localhost:8080',    'Access-Control-Allow-Headers'       =>'Origin, Content-Type, Cookie, X-CSRF-TOKEN, Accept, Authorization, X-XSRF-TOKEN',    'Access-Control-Allow-Methods'       =>'GET, POST, PUT, DELETE',    'Access-Control-Allow-Credentials'   => 'true']);

安装视图

composer require topthink/think-view

输出html

return View::fetch('index', [    'name'  => 'ThinkPHP',    'email' => 'thinkphp@qq.com']);

html输出

{$name}

数据库Db

使用需要引入use think\facade\Db;

不需要写表前缀

$list = Db::name('user')->where('id', 1)->find();

必须写表前缀

$list = Db::table('dade_user')->where('id', 1)->find();

插入，添加Db::execute("insert into dade_order_goods(name,price,state,stock,items,richtext,dade) values ($name,$price,$state,$stock,$items,$richtext,$date)");分页$pageSize = (1-1)*10;$list = Db::query("select * from dade_order_goods limit $pageSize,10");根据id倒序order by id desc分页$pageSize = (1-1)*10;$list = Db::query("select * from dade_order_goods order by id desc limit $pageSize,10");加条件select * from dade_user_withdrawal where (state=2) order by id desc limit $pageSize,7查总数count(*)$count = Db::query("select count(id) from dade_order_goods");//总数数组$length = ceil($count[0]['count(id)']/10);//总页数删除Db::execute("delete from dade_order_goods where id=$id");修改 Db::execute("update dade_order_goods set name=$name,price=$price where id=$id");  一次写入100条 Db::table('cdj_pindex_house') ->limit(100) ->insertAll($info);

模型

创建模型

php think make:model admin\model\User

//定义idprotected $pk = 'uid';//数据库表protected $name = 'user';//数据库表这个需要写表前缀protected $table = 'think_user';引入use app\admin\model\User as Users;查询$list = User::where('status', 1)->limit(3)->order('id desc')->select();查两列$user = User::column('id,user');添加$user = User::create([    'name'  =>  'thinkphp',    'email' =>  'thinkphp@qq.com']);批量添加$user = User::create([    'name'  =>  'thinkphp',    'email' =>  'thinkphp@qq.com'], ['name', 'email']);更新User::where('id', 1)->update(['name' => 'thinkphp']);删除User::destroy(1);支持批量删除多个数据User::destroy([1,2,3]);

倒序查询

Users::order('id desc')->select();

查询多少条分页

$ids = $request->get('ids');$list = Users::page($ids,10)->order('id desc')->select();$page  = Users::count();$length = ceil($page/10);$listpage = [$list,$page,$length];return json($listpage);//统计查询出多少条$page = Users::where('user', 'like', '%'.$search .'%')->select()->count();

模型关系查询一对多，一对一

正向

一对多public function orsers(){    return $this->hasMany(Order::class,'store_id');}一对一public function stores(){    return $this->hasOne(Store::class, 'store_id');}

反向

public function stores(){    return $this->belongsTo(Store::class,'store_id');}//查询$idsv = 1；$list = Users::with('stores')->page($idsv,10)->order('id desc')->select();

合并在一个数组里查询

$list = Orders::withJoin(['stores'  => ['id', 'user']])->page($idsv,10)->order('id desc')->select();

模型创建修改时间戳转换

protected $type = [   'tiem2'  =>  'timestamp:Y/m/d H:i:s',];protected $createTime = 'tiem';protected $updateTime = 'tiem1';protected $dateFormat = "Y-m-d H:i:s";

PHP写入文件excel

第一种file_put_contents("excel/tests.xlsx", $shuj, FILE_APPEND);

第二种（写入一次w,追加写入a）$file = fopen("excel/test1.xlsx","a");fwrite($file,"数据");fclose($file);

php获得当前时间

$userlevel['time'] = date('Y-m-d H:i:s');$userlevel['time'] = time();第二种写法$t=time();date("Y-m-d H:i:s",$t);日期转时间戳strtotime(date("Y-m-d H:i"));//获得7天前时间$stime = mktime(0,0,0,date('m'),date('d')-7,date('Y'))-1;$time = date("Ymd",$stime);

接收iview上传图片

$file = $request->file('file');$savename = \think\facade\Filesystem::disk('public')->putFile( 'topic', $file);echo $savename;

php生成随机数

$code = rand(10000, 99999);

保存数组解码数组

// 写入数据库之前$staff_serialize = serialize($staff);            // 序列化成字符串$staff_json = json_encode($staff);               // JSON编码数组成字符串// 读取数据库后$staff_restore = unserialize($staff_serialize);  // 反序列化成数组$staff_dejson = json_decode($staff_json, true);  // JSON解码成数组

数组追加

$list = [$Goodsid,$result];$items = unserialize($order[0]['item']);$itemss = array_merge($items,$list);结果[3, "可以是的11111", 3, "可以是的11111", 3, "可以是的11111", 5, "可以是的1111111"]0: 31: "可以是的11111"2: 33: "可以是的11111"4: 35: "可以是的11111"6: 57: "可以是的1111111"

理想二维追加

$list = [[$goodsid,$result]];$items = unserialize($order[0]['item']);$itemss = array_merge_recursive($items,$list);结果[[5, "可以是的1111111"], [5, "可以是的1111111"], [2, "可以是的"], [2, "可以是的"], [2, "可以是的"], [2, "可以是的"]]0: [5, "可以是的1111111"]1: [5, "可以是的1111111"]2: [2, "可以是的"]3: [2, "可以是的"]4: [2, "可以是的"]5: [2, "可以是的"]

获得url

$_SERVER[‘HTTP_HOST’]

php跳转

header("Location:".$url);

微信授权获得网站输出

$url = "https://api.weixin.qq.com/sns/oauth2/access_token?appid=$appid&secret=$secret&code=$code&grant_type=authorization_code";$weix = file_get_contents($url);//获得网页输出

Redis缓存，缓存

use think\facade\Cache;//引入$security = $user."_security";Cache::set($security, $users[0]['jurisdiction'],36000);//缓存权限$securitys = Cache::get($security);//查

php拆分成数组

$Plain = “aaa|666|777”；

$list=explode{(}^{\prime }{|}^{\prime },$Plain);

数组降序，升序

$guys = array(    array('name'=>'jake', 'score'=>80, 'grade' =>'A'),    array('name'=>'jina', 'score'=>70, 'grade'=>'A'),    array('name'=>'john', 'score'=>70, 'grade' =>'A'),    array('name'=>'ben', 'score'=>20, 'grade'=>'B'));//例如我们想按成绩倒序排列，如果成绩相同就按名字的升序排列。*//这时我们就需要根据$guys的顺序多弄两个数组出来：*$scores = array(80,70,70,20);$names = array('jake','jina','john','ben');//然后,排序顺序标志 SORT_DESC 降序；SORT_ASC 升序array_multisort($scores, SORT_DESC, $names, $guys);//测试成功$list = 二维数组；$scores = array();$names = array();foreach ($list as $key=>$it){$scores[$key] =  $it['mobile'];$names[$key] = $it['id'];} array_multisort($scores, SORT_DESC, $names, $list);直接输出$list就可以

二维数组转一维数组，转字符串

//$list1是二维数组$array = array_column($list1, 'jurisdiction_id');//转一维$implode = implode(",",$array);//转字符串逗号隔开

文件锁定一个一个来

$file = 'static/temp.txt';//文件路径$fp = fopen($file,'a');//打开文件//排队一个一个来，设定if(flock($fp,LOCK_EX)){    for($i = 0;$i < 5;$i++)    {        fwrite($fp, "11111111n");        sleep(1);    }    flock($fp,LOCK_UN);//释放设定}fclose($fp);//关闭文件，释放

url反斜杠转正斜杠

$date['carousel'] = str_replace("\\",'/',$date['carousel']);
