Laravel's Dependency Injection Container in Depth

Translations: Korean (by Yongwoo Lee)

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).

Indexes are best used on columns that are frequently used in where clauses, and in any kind of sorting, such as "order by".

If we assign ID as a primary key, we don't need one there.
