Laravel Artisan 命令行:查看命令帮助信息 2 个改进


如何获得一个 Artisan 命令的帮助信息?


每个 Artisan 命令都包含有帮助信息,我们只需通过 help 命令或 -h--help 选项即可显示一个命令的帮助信息。

比如查看 migrate 命令的帮助信息,可通过如下方式:

通过 help 后带要查看帮助的命令名:

$ php artisan help migrate

通过在命令后加 -h 选项:

$ php artisan migrate -h

通过在命令后加 --help 选项:

$ php artisan migrate --help
