What are best practices for effectively using external PHP classes in a project?

When using external PHP classes in a project, it is essential to follow best practices to ensure smooth integration and efficient utilization of the classes. One key practice is to properly autoload classes using an autoloader to avoid manual require/include statements for each class. Additionally, it is important to carefully review the documentation of the external classes to understand their functionalities and how to use them effectively in the project. 

// Autoloading classes using Composer's autoloader
require 'vendor/autoload.php';

// Example of using an external PHP class
use External\ClassName;

$object = new ClassName();
$object->someMethod();
