What are the best practices for organizing file paths in a PHP project, especially in relation to the public directory and vendor files?

When organizing file paths in a PHP project, it is best practice to separate public files (such as images, stylesheets, and JavaScript) from sensitive files that should not be directly accessible by users. The public directory should serve as the document root for the web server, while vendor files (such as third-party libraries) should be kept outside of the public directory for security reasons. 

define('PUBLIC_PATH', __DIR__);
define('ROOT_PATH', dirname(__DIR__));
define('VENDOR_PATH', ROOT_PATH . '/vendor');

// Example usage:
// Include a file from the vendor directory
require_once VENDOR_PATH . '/autoload.php';

// Link to a stylesheet in the public directory
echo '<link rel="stylesheet" href="' . PUBLIC_PATH . '/css/styles.css">';
