推荐答案

解决方案

正如这里 最新版本的 Laravel 6、7 和 8 所解释的那样php 8 所需的更改.您所要做的就是:

As explained here latest version of laravel 6, 7 and 8 has made changes required for php 8. all you have to do is:

1- 将 php 8 添加到您的 composer.json(我保留了 v7.4，以防生产服务器尚不支持 php 8)

1- add php 8 to your composer.json (I've kept v7.4 just in case production server does not support php 8 yet)

"php": "^7.4|^8.0",

2- 运行 composer update 将你的 Laravel 更新到最新版本

2- to run composer update to update your laravel to the latest version

composer update

3- 确保更新以下库，因为它们存在于所有 Laravel 应用程序中

3- make sure update the following libraries since they exist in all laravel applications

PHP to php:^8.0
Faker to fakerphp/faker:^1.9.1
PHPUnit to phpunit/phpunit:^9.3

4- 检查是否有任何其他需要更新的库，如果它们不支持 php 8，请贡献.但是你应该使用大多数库，因为它们有活跃的贡献者.

4- check for any other library which needs to be updated, contribute if they haven't supported php 8. but you should be good to go with most of the libraries since they have active contributors.

解释问题

如此处所述

PHP 8 对 PHP 类型系统进行了多项改进，例如引入了联合类型、混合类型等.

PHP 8 introduces several improvements in PHP type systems such as the introduction of Union Types, mixed type, and a few more.

通过这些更改，反射 API 中的某些方法ReflectionParameter 产生错误的结果.

With these changes, certain methods in Reflection API's ReflectionParameter yield incorrect results.

在 PHP 8 中，以下来自 ReflectionParameter 类的方法是已弃用:

In PHP 8, the following methods from ReflectionParameter class is deprecated:

ReflectionParameter::getClass()
ReflectionParameter::isArray()
ReflectionParameter::isCallable()

ReflectionParamter::getType() 是推荐的替代方法弃用的方法.此方法在 PHP 7.0 及更高版本中可用.

ReflectionParamter::getType() is the recommended way to replace the deprecated methods. This method is available in PHP 7.0 and later.
