class Configuration { public static $timezone = 'America/New_York'; } // To use: date_default_timezone_set(Configuration::$timezone);
class Configuration { public static $apiKey = 'abc123'; public static $apiSecret = 'xyz789'; } // To use: $client = new Client(['apiKey' => Configuration::$apiKey, 'apiSecret' => Configuration::$apiSecret]);In this example, we define two static properties `$apiKey` and `$apiSecret` in the `Configuration` class and set their default values to `abc123` and `xyz789`, respectively. We then use these values to initialize an API client. The library or package that provides these examples is not specified, as static options are a language feature of PHP itself.
