Overview of this book

This book is intended for PHP web developers who have an interest in Laravel and who know the basics of the framework in theory, but don't really know how to use it in practice. No experience of using frameworks is required, but it is assumed you are at least familiar with building dynamic websites in PHP already.

Retrieving data

Eloquent provides you with numerous ways to fetch records from your database, each with their own appropriate use case. You can simply fetch all records in one go; a single record based on its primary key; records based on conditions; or a paginated list of either all or filtered records.

To fetch all records, we can use the aptly-named all method:

use App\Cat;
$cats = Cat::all();

To fetch a record by its primary key, you can use the find method:

$cat = Cat::find(1);

Along with the first and all methods, there are aggregate methods. These allow you to retrieve aggregate values (rather than a record set) from your database tables:

use App\Order;

$orderCount    = Order::count();
$maximumTotal  = Order::max('amount');
$minimumTotal  = Order::min('amount');
$averageTotal  = Order::avg('amount');
$lifetimeSales = Order::sum('amount');

Filtering records

Eloquent also ships with a feature-rich query builder that allows you to build queries in code, without having to write a single line...
