You can use the Process component provided by Symfony: http://symfony.com/doc/current/components/process.html
您可以使用 Symfony 提供的 Process 组件：http: //symfony.com/doc/current/components/process.html
The component is used by Laravel itself, so it can be loaded directly.
该组件是 Laravel 自己使用的，所以可以直接加载。
If you use it(instead of php's exec()function), you'll be able to unit test the code that calls shell commands.
如果您使用它（而不是 php 的exec()函数），您将能够对调用 shell 命令的代码进行单元测试。

It all depends on what operating system you are using. php already has a few functionsto execute shell commands.
这完全取决于您使用的操作系统。php 已经有一些函数来执行 shell 命令。
Laravel has a build in task runner for sshcommands.
