ThinkPHP6.x升级到ThinkPHP8.x教程
一、升级前准备
以下是tp6.1.x升级到tp8.0.x的步骤，如果你目前版本是tp6.0.x的，请先将期升级到tp6.1.x切记！！
6.0升级到6.1版本
由于安全性原因，6.1版本移除核心对think-filesystem库的依赖，因此6.0版本升级至6.1版本后，需要单独安装`topthink/think-filesystem`库。
二、查看PHP的版本，tp8要求php >= 8.0
1、查看php版本：
liuhongdi@lhdpc:~$ /usr/local/soft/php8/bin/php --version
PHP 8.1.1 (cli) (built: Dec 20 2021 16:12:16) (NTS)
Copyright (c) The PHP Group
Zend Engine v4.1.1, Copyright (c) Zend Technologies
with Zend OPcache v8.1.1, Copyright (c), by Zend Technologies
当前版本是 8.1.1 ，显然符合条件
2、查看当前项止的thinkphp版本:
liuhongdi@lhdpc:/data/php/tpapibase$ php think version
v6.1.0
三、升级ThinkPHP开始
1、升级原项目到可用的最新版本:
liuhongdi@lhdpc:/data/php/tpapibase$ composer update topthink/framework

liuhongdi@lhdpc:/data/php/tpapibase$ php think version
v6.1.4
可以看到升级完成后版本是v6.1.4
2、修改composer.json
"require": {
"php": ">=8.0.0",
"topthink/framework": "^8.0",
"topthink/think-orm": "^3.0",
"topthink/think-filesystem": "^2.0"
},
"require-dev": {
"symfony/var-dumper": ">=4.2",
"topthink/think-trace":"^1.0"
},
对require需要用到的库的版本调整，我的配置版本号如上，
“topthink/think-filesystem”: “^2.0”, 这一行是我手动添加上的,
说明：这些版本号是从哪里来的？
用下面的命令新创建一个thinkphp8项目，从composer.json中就看到了
liuhongdi@lhdpc:/data/php$ composer create-project topthink/think tp8
3、删除composer.lock
liuhongdi@lhdpc:/data/php/tpapibase$ rm composer.lock4、升级前查看当前各库的版本:
liuhongdi@lhdpc:/data/php/tpapibase$ composer show

5、升级:
liuhongdi@lhdpc:/data/php/tpapibase$ composer install
