MongoDB Aggregation in PHP

Overview

In this unit, you'll learn how to perform basic aggregation with PHP by using MongoDB's aggregation framework. First, you'll learn what aggregation is and explore the components of an aggregation pipeline. Next, you'll learn how to build a pipeline that uses the $match and $group stages. Finally, you'll explore the $sort and $project stages and build a pipeline that uses them.
