In what scenarios would it be more beneficial for clients to directly edit INI files rather than PHP files for configuration settings in PHP projects?

In scenarios where clients need to easily modify configuration settings without needing to understand PHP code, it may be more beneficial for them to directly edit INI files. This allows clients to make changes to settings such as database connections or file paths without the risk of accidentally altering the PHP code structure.

// Example of loading configuration settings from an INI file in a PHP project

$config = parse_ini_file('config.ini');

// Accessing configuration settings
$db_host = $config['db_host'];
$db_user = $config['db_user'];
$db_pass = $config['db_pass'];
$db_name = $config['db_name'];
