What are the potential drawbacks of storing configuration settings in a MySQL database instead of using config files in PHP?

Storing configuration settings in a MySQL database can introduce additional complexity and potential points of failure in your application. It can also lead to slower performance as the application needs to query the database for each configuration setting. Using config files in PHP is a simpler and more efficient way to manage configuration settings.

// Example of how to store configuration settings in a PHP config file

$config = [
    'db_host' => 'localhost',
    'db_user' => 'root',
    'db_pass' => 'password',
    'db_name' => 'my_database'
];

// Usage example
echo $config['db_host']; // Output: localhost
