For example, in the laravel project, when I run the command composer i, all the packages which were specified in composer.json will be installed in the vendor folder.
As long as each of them already includes the license file in the source code, I don't need to worry about the "License and copyright notice" condition anymore because all of them already include the license file in the licensed material(which is the source code of that package) after installing via composer, right? If not, please show me how to do that.
Then I can add my own license file for my project in the main source code and use it for whatever I want (private use, open source, commercial use...).
