从代码运行`php composer.phar dump-autoload` - Laravel 5.4

Question

I'm trying to run these command from code, but having some trouble finding out how.

• php composer.phar dump-autoload -o
• php composer.phar require 'vendor/some-package'
• php composer.phar update 'vendor/some-package'

EDIT

Forgot to mention, that I don't want to use the exec function because of potential risk and the fact that's blocked on most servers by default.

I did manage to download the .phar file from code, but not how to run these commands. I'm trying to build a friendly as possible solution and don't want use to dumpautoload manually after installing something etc.

Code to download

 $composerPath = base_path('composer.phar');
 copy('https://getcomposer.org/composer.phar', $composerPath);

I have found a working solution. You can call these command with Symphony's process component.

$process = new \Symfony\Component\Process\Process('php composer.phar autoload-dump');
$process->setWorkingDirectory(base_path());
$process->run();
