Laravel Companion
Laravel Companion
A Guide to Helpers, Collections And More
About the Book
The Laravel framework contains many useful helper functions, features and utility classes (such as Collections) - not all of these are well known. This book exposes these helper utilities to encourage accelerated application development using the Laravel framework (version 5.3). Through the Laravel Companion you will learn about collections, facades, application helper functions, request and URL helper functions and much, much more.
If you've ever thought there "has to be an easier way" - there probably is in the form of a helper utility.
