Are there any best practices for organizing and structuring PHP scripts that include or require other scripts?

When organizing and structuring PHP scripts that include or require other scripts, it is best practice to use a consistent file structure and naming convention. This can help maintain code readability and organization. Additionally, it is recommended to use namespaces to avoid naming conflicts and improve code modularity.

// Example of organizing and structuring PHP scripts with namespaces

// File: main.php
namespace MyApp;

require_once 'functions.php';

use MyApp\Functions;

// Your code here

// File: functions.php
namespace MyApp;

class Functions {
    // Your functions here
}
