Laravel's Dependency Injection Container in Depth

Laravel has a powerful Inversion of Control (IoC) / Dependency Injection (DI) Container. Unfortunately the official documentation doesn't cover all of the available functionality, so I decided to experiment with it and document it for myself. The following is based on Laravel 5.4.26 - other versions may vary.

Introduction to Dependency Injection

I won't attempt to explain the principles behind DI / IoC here - if you're not familiar with them you might want to read What is Dependency Injection? by Fabien Potencier (creator of the Symfony framework).

Accessing the Container

openapi-generator version
openapi-generator help
openapi-generator list
openapi-generator help generate

openapi-generator generate -g spring -i api.yml -o build/spring_server

openapi-generator generate -g php -i api.yml -o build/php_client

Summary

the iMac in the home was always yelling to upgrade the OS version for a long time.
but I ignored the alert.
Today I had a spare time and saw that alert again. I pressed "upgrade" and I quickly realized that I was mad.
so I was panicked. Even though I cannot remember what I have tried though, it was apparent that problem was arose because of the new file system(APFS) adopted starting from High Sierra.
(deep sigh) myself should be blamed.
