有人对env个变量有问题吗？由于某些原因，每次我使用帮助器env('VARIABLE')都会返回null.这件事发生得非常出乎意料，我真的不知道原因.重新启动Apache/IDE/计算机无法正常工作.

The solution is simple, but neither the IDE nor the debugger says anything about it. It just returns null. When you use php artisan config:cache, according to the documentation:
If you execute
php artisan config:cachecommand during your deployment process, you should be sure that you are only calling theenv()function from within your configuration files.
Obviously I have env variables outside the config files, so after caching I was not able to use it outside anymore. The php artisan config:clear puts it back to work.
What I've found more about the usage of env, that it should be used only within config files. You can access env variables from the rest of the project using other helper method config(). Be sure to assign it to another key in config file, e.g. 'key' => env('CACHE_DRIVER')
更重要的是，您必须记住每次更改.env文件时都要运行php artisan config:cache.在缓存新值之前，Laravel不会加载新值.如果没有缓存，则无需执行此操作.
