What are the best practices for organizing and including PHP files in a project to avoid conflicts and errors?

To avoid conflicts and errors when organizing and including PHP files in a project, it is important to follow best practices such as using namespaces, autoloading classes, and organizing files into logical directories. This helps to prevent naming collisions, improve code readability, and make it easier to maintain and update the project. 

// Example of using namespaces and autoloading classes in PHP

// File: MyClass.php
namespace MyNamespace;

class MyClass {
    // Class implementation
}

// File: index.php
require_once 'vendor/autoload.php';

use MyNamespace\MyClass;

$myObject = new MyClass();
