提问by AnonS
I need to execute shell commands from controller , but not only for files inside the project , ex. system('rm /var/www/html/test.html') or system('sudo unzip /var/www/html/test.zip');
我需要从控制器执行 shell 命令，但不仅限于项目内的文件，例如。system( 'rm /var/www/html/test.html') 或 system( 'sudo unzip /var/www/html/test.zip');
I call the function but nothing happen , any idea how to execute external shell commands from controller like removing one file in another directory?

If you're wanting to run commands from your PHP application I would recommend using the Symfony Process Component:
如果您想从 PHP 应用程序运行命令，我建议使用Symfony Process Component：
- Run
composer require symfony/process - Import the class in to your file with
use Symfony\Component\Process\Process; Execute your command:
$process = new Process(['rm', '/var/www/html/test.html']); $process->run();
- 跑
composer require symfony/process - 将类导入到您的文件中
use Symfony\Component\Process\Process; 执行你的命令：
$process = new Process(['rm', '/var/www/html/test.html']); $process->run();
Alternatively, (if the process running php has the correct permissions) you could simply use PHP's unlink()function to delete the file:
或者，（如果运行 php 的进程具有正确的权限）您可以简单地使用 PHP 的unlink()函数来删除文件：
unlink('/var/www/html/test.html');

I would do this with what the framework already provide:
我会用框架已经提供的东西来做到这一点：
1) First generate a command class:
1）首先生成一个命令类：
php artisan make:command TestClean
This will generate a command class in App\Console\Commands
这将在 App\Console\Commands 中生成一个命令类
Then inside the handle method of that command class write:
然后在该命令类的句柄方法中写入：
@unlink('/var/www/html/test.html');
Give your command a name and description and run:
给你的命令一个名称和描述并运行：
php artisan list
Just to confirm your command is listed.
只是为了确认您的命令已列出。
2) In your controller import Artisan facade.
2) 在您的控制器中导入 Artisan 外观。
use Artisan;
3) In your controller then write the following:
3）然后在你的控制器中写下以下内容：
Artisan::call('test:clean');
