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).

A list of stupid email client quirks as I discover them

TL;DR - Gmail sucks balls.

Outlook ignores display:block on inline elements, e.g. span. Use default block elements like div or p.
Outlook 2003/2007 doesn't support background-image. Use a fallback colour and make sure the text is still legible.
Gmail supports background-image but ignores background-position. Stupid Gmail.
Gmail's mobile app ignores media queries. Yes, a mobile app ignores media queries. Did I mention Gmail is stupid?
Gmail clips your email if it thinks it's too long. The file size limit is around 100kb but keep it under 80kb to be safe. Images don't count. Minify your HTML.

	* Plugin: StreamlineFoundation

	* Description: Provides scheduling mechanics including creating a schedule, testing if a specific moment is part of the schedule, moving back
	* and forth between scheduled moments in time and translating the created schedule back to a human readable form.
	*
	* Usage: ::fromCronString() creates a new Schedule class and requires a string in the cron ('* * * * *', $language) format.
