如何在 Laravel 5.7 中更改数据库

Question

I created a new project and set up my database accordingly in the .env file.

DB_CONNECTION=mysql
DB_HOST=127.0.0.1
DB_PORT=8889
DB_DATABASE=example_olddb
DB_USERNAME=example_user
DB_PASSWORD=example_password

After much development, I want to change my database to a new database. So I edited the '.env' file again.

DB_CONNECTION=mysql
DB_HOST=127.0.0.1
DB_PORT=8889
DB_DATABASE=example_newdb///<-- change here
DB_USERNAME=example_user
DB_PASSWORD=example_password

However, I got the following error.

SQLSTATE[HY000] [1049] Unknown database 'example_olddb'

It used to work in Laravel 5.5 and 5.6 , but not now in 5.7 . I tried to clear the cache, but same error persists. How can I resolve this issue?

.env编辑完成后，您可以使用以下 artisan 命令清除配置缓存： php artisan config:cache
