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).

document.getElementsByTagName('button')[0].onclick = function () {
   scrollTo(document.body, 0, 1250);   
}
    
function scrollTo(element, to, duration) {
    var start = element.scrollTop,
        change = to - start,
        currentTime = 0,
        increment = 20;

            if ($value instanceof \Closure) {
                $closureReflection = new \ReflectionFunction($value);
                $value = sprintf(
                    '(Closure at %s:%s)',

#Introduction If you're a php developer on ubuntu, there comes the time where you have to install/reinstall your system. I did it already a few times and i decided to write down the steps for a typical web developer stack with php. This is for a developer machine and not for a live environment!

I hope it helps you too!

fyi @mheiniger and me started with an installer here: https://github.com/mheiniger/webdev-setup
