Composer is a tool for dependency and libraries management in PHP.
It helps us installing/updating various requirements/components for our app such as Laravel framework, Doctrine, etc.. Third party libraries can be installed easily with help of composer.
Note: All the dependencies are noted in a composer.json file which is placed in the source folder.
Command line interface(CLI) used in Laravel is called Artisan.
It provides a number of helpful commands that can assist you while you build your application. To view a list of all available Artisan commands, you may use the list command:
php artisan list
To view a help screen, precede the name of the command with help:
php artisan help migrate
