$config = new Config(); $config->setConfigurationValues([ 'debug' => true, 'database' => [ 'host' => 'localhost', 'username' => 'root', 'password' => 'p@ssword123', 'database' => 'mydatabase' ] ]);In this example, we create a new `Config` object and set two configuration options: `debug` is set to `true`, while `database` is set to an array of database connection details. The `setConfigurationValues` method is from the `Config` class/package/library. Different PHP frameworks may include their own versions of this method, but it is also possible to create your own `Config` class and use the `setConfigurationValues` method within it.
