How to Retrieve Document Data from Database in PHP
In web development, especially when working with PHP, you may often encounter the need to handle data in a structured format. A common scenario arises when you have a multidimensional array and need to fetch specific data from a database. This guide will guide you through the process of retrieving document data from a database and populating a multidimensional array with this information, specifically focusing on how to get the documentos part of your data structure.
Understanding the Problem

You need to fetch the documentos part of this array from a database using a foreach loop.
Step-by-Step Solution
Step 1: Prepare Your Database
