In PHP development, what are the best practices for organizing and managing code snippets to improve efficiency and maintainability in the long run?

Organizing and managing code snippets in PHP development is crucial for improving efficiency and maintainability in the long run. One of the best practices is to create separate files for different functionalities or components, such as functions, classes, or configurations. This allows for better organization, easier maintenance, and reusability of code snippets.

// Example of organizing code snippets in PHP

// functions.php
function calculate_sum($a, $b) {
    return $a + $b;
}

// classes.php
class User {
    private $name;

    public function __construct($name) {
        $this->name = $name;
    }

    public function get_name() {
        return $this->name;
    }
}

// config.php
define('DB_HOST', 'localhost');
define('DB_USER', 'root');
define('DB_PASS', 'password');
define('DB_NAME', 'database_name');
