What are some best practices for organizing files and directories when working with PHP scripts?

When working with PHP scripts, it is important to organize files and directories in a structured manner to maintain code readability and accessibility. One common best practice is to separate different types of files, such as classes, functions, and templates, into their respective directories. Additionally, creating a clear naming convention for files and directories can help developers easily locate and identify specific files.

// Example of organizing files and directories in a PHP project

// Directory structure:
// - classes/
// - functions/
// - templates/

// Example usage of classes
require_once 'classes/User.php';
$user = new User();

// Example usage of functions
require_once 'functions/utils.php';
echo formatData($data);

// Example usage of templates
require_once 'templates/header.php';
include 'templates/home.php';
require_once 'templates/footer.php';
