[ 'host' => 'localhost', 'username' => 'root', 'password' => '', 'database_name' => 'my_database' ] ]; // Update configuration $config['database']['password'] = 'new_password'; // Clear the configuration cache clearstatcache(); // Reload configuration $config = include 'config.php'; ?>
[ 'host' => 'localhost', 'username' => 'root', 'password' => '', 'database_name' => 'my_database' ] ]); // Update configuration $config->set('database.password', 'new_password'); // Clear the configuration cache $config->clearCache(); // Reload configuration $config->load(); ?>In this example, the `Repository` class from the Laravel framework is used to manage the configuration. The `set()` method is used to update the password for the database, and the `clearCache()` method is used to clear the configuration cache. Finally, the `load()` method is used to reload the configuration. Package library: The config clear function is a built-in function in PHP and is not part of any external package library. However, there are many third-party packages and libraries that provide more advanced configuration management features in PHP, such as Symfony's Config component or Laravel's Configuration package.
