ThinkPHP6.0 Miscellaneous
1. Session
To use the
Sessionclass, you must use the facade method (think\facade\Session) CallingThe new version does not support operating the native
$_SESSIONarray and all functions starting withsession_. It can only be called through the Session class (or assistant Function) to operate
1. Configuration file session.php
return [ // session name 'name' => 'PHPSESSID', // SESSION_ID的提交变量,解决flash上传跨域 'var_session_id' => '', // 驱动方式 支持file cache 'type' => 'file', // 存储连接标识 当type使用cache的时候有效 'store' => null, // 过期时间 'expire' => 1440, // 前缀 'prefix' => '', ];
2. Open Session
Middleware
app\middleware.phpFile
\think\middleware\SessionInit::class
3. Settings
session supports multi-level array operations
Session::set('name','欧阳克');
// Session数组
Session::set('admin.name','欧阳克');
Session::set('admin.uid',1);4. Read
// 获取全部Session
Session::all();
// 获取Session中name的值
Session::get('name');5. Delete
Session::delete('name');6. Get the value and delete
Session::pull('name');7. Login example
New login.php file
namespace app\controller;
use think\facade\View;
use think\facade\Db;
use think\facade\Request;
use think\facade\Session;
class Login{
public function index(){
if(Request::method() == 'POST'){
$all = Request::param();
$admin = Db::table('shop_admin')->where('account',$all['account'])->find();
if(empty($admin)){
echo json_encode(['code'=>1,'msg'=>'未找到管理员']);
exit;
}
if(md5($all['pwd']) != $admin['password']){
echo json_encode(['code'=>1,'msg'=>'密码错误']);
exit;
}
Session::set('uid',$admin['uid']);
Session::set('account',$admin['account']);
echo json_encode(['code'=>0,'msg'=>'登陆成功']) ;
}else{
$title = '商城';
View::assign([
'title' => $title
]);
return View::fetch();
}
}

return View::fetch();
}2. Cookie
To use the Cookie class, you must use the facade method (
think\facade\Cookie) Call the# configuration file located in the cookie.php file in the configuration directory. No manual initialization is required. The system will automatically initialize Cookie before calling. Work
1. Using Cookie
// 设置Cookie 有效期为 3600秒
Cookie::set('name', '欧阳克', 3600);
// 永久保存Cookie
Cookie::forever('name', '欧阳克');
//删除cookie
Cookie::delete('name');
// 读取某个cookie数据
Cookie::get('name');2. Cookie configuration file
cookie.php file in the config directory
return [ // cookie 保存时间 'expire' => 0, // cookie 保存路径 'path' => '/', // cookie 有效域名 'domain' => '', // cookie 启用安全传输 'secure' => false, // httponly设置 'httponly' => false, // 是否使用 setcookie 'setcookie' => true, ];
3. Cache
To use the cache, you must use the facade method (
think\facade\Cache) to callBuilt-in supported cache types include
file,memcache,wincache,sqlite,redis
1. Use cache
// 缓存在3600秒之后过期
Cache::set('number', 10, 3600);
// number自增（步进值为3）
Cache::inc('number',3);
// number自减（步进值为1）
Cache::dec('number');
// 获取缓存
Cache::get('number');
// 删除缓存
Cache::delete('number');
// push 追加缓存
Cache::set('name', ['欧阳克','朱老师']);
Cache::push('name', '西门大官人');
// 获取并删除缓存
Cache::pull('name');
// 清空缓存
Cache::clear();2. Cache configuration file
config directory cache.php File
return [ // 默认缓存驱动 'default' => 'file', // 缓存连接方式配置 'stores' => [ 'file' => [ // 驱动方式 'type' => 'File', // 缓存保存目录 'path' => '', // 缓存前缀 'prefix' => '', // 缓存有效期 0表示永久缓存 'expire' => 0, // 缓存标签前缀 'tag_prefix' => 'tag:', // 序列化机制 例如 ['serialize', 'unserialize'] 'serialize' => [], ], // redis缓存 'redis' => [ // 驱动方式 'type' => 'redis', // 服务器地址 'host' => '127.0.0.1', ], // 更多的缓存连接 ], ];
4. Public Controller

use think\facade\View;
use think\facade\Db;
use think\facade\Session;
public function initialize(){
$session = Session::all();
if(empty($session['uid'])){
echo '<script type="text/javascript">alert("请登录！");window.location.href = "/index.php/login/index"; </script>';
exit;
}
$login = $session['account'];

}5. Facade
The facade provides a static calling interface for (dynamic) classes in the container. Compared with traditional static method calling, it has For better testability and extensibility, you can define a
for any non-static class libraryfacadeclass
| （动态）类库 | Facade类 |
| think\App | think\facade\App |
| think\Cache | think\facade\Cache |
| think\Config | think\facade\Config |
| think\Cookie | think\facade\Cookie |
| think\Db | think\facade\Db |
| think\Env | think\facade\Env |

1. Facade class
The facade provides a static calling interface for (dynamic) classes in the container. Compared with traditional static method calling, it brings better Testability and scalability
The system has defined Facade for most core class libraries, so you can access these system classes through Facade
use think\facade\App;
use think\facade\Db;
use think\facade\View;
use think\facade\Request;
use think\facade\Session;
class Index{
public function index(){
// 数据库操作
$select = Db::table('shop_goods')->select();
// 请求对象
$param = Request::param();
// Session
$session = Session::all();
// 视图
return View::fetch();
}
} 2. (Dynamic) Class Library
use think\App;
use think\Db;
use think\View;
use think\Request;
use think\Session;
class Index{
public function index(View $view,Db $db){
$select = $db->table('shop_goods')->select();
$view->assign([
'name' => '欧阳克',
'select' => $select
]);
return $view->fetch();
}
}6. Assistant Function
Thinkphp system encapsulates the assistant function for some common operation methods

| download | Get\think\ response\Download object instance |
| dump | Browser-friendly variable output |
| env | Get Environment variables |

| lang | Get language variable value |
| parse_name | String naming style conversion |
| Redirect output | |
| Get the current Request object | |
| Instantiate the Response object | |
| Session management | |
| Generate form token output | |
| Record log information | |
| Get all the traits referenced in a trait | |
| Url generation | |
| Instantiated validator | |
| Rendering template output | |
| display | Rendering content output |
| xml | XML data output |
| app_path | Current application directory |
| base_path | Application base directory |
| config_path | Application configuration directory |
| public_path | web root directory |
| root_path | Application root directory |
| runtime_path | Application runtime directory |
7. Debugging1. Debug mode and Trace debugging# #// Get input data, same effect as Request::param()
$param = input();// Variable debugging output and interrupt execution$ shop = Db::table('shop_goods')->select();halt($shop);// Rendering template output, with View::fetch() effect Samereturn view();
- ##root
- .env
file in the directory
APP_DEBUG = true
Preparation: Turn off debugging mode after formal deployment
2. Variable debugging
- ThinPHP has built-in
- dump
Debugging method
dump($shop);
