return [ 'database' => [ 'host' => 'localhost', 'username' => 'root', 'password' => '', 'database' => 'mydatabase', ], 'debug' => true, ];
use Cake\Core\Configure; $config = include 'app_config.php'; $exists = Configure::check('database.host'); // true $host = Configure::read('database.host'); // 'localhost' $debug = Configure::read('debug'); // trueIn this example, we first load the configuration data from the file and assign it to the `$config` variable. We then use the `check()` method to see if the `database.host` key exists, which returns `true`. We also use the `read()` method to retrieve the `database.host` value and the `debug` value. Based on the use of `use Cake\Core\Configure;` and the class `Configure` being used, it is likely safe to assume that this example is using the CakePHP framework.
