Are there any best practices for organizing and using libraries in PHP projects?

When organizing and using libraries in PHP projects, it is best practice to use namespaces to avoid naming conflicts and improve code readability. Additionally, using Composer for dependency management can streamline the process of including external libraries in your project. Lastly, creating a clear directory structure for your libraries can make it easier to locate and manage them within your project.

// Example of using namespaces to organize libraries
namespace MyProject;

use Vendor\Library;

// Example of using Composer to include external libraries
require 'vendor/autoload.php';

// Example of creating a directory structure for libraries
- src/
  - MyProject/
    - Library1.php
    - Library2.php
- vendor/
