$config = getConfig('/path/to/config/file.ini'); $value = $config['database']['username'];
$config = getConfig('ENV'); $value = $config['database']['password'];In this example, we're retrieving data from an environment variable called "ENV". We then use array notation to access a specific value, in this case the password used to connect to the database. This example does not require a package or library as it is a built-in feature of PHP. In both examples, getConfig() allows developers to easily retrieve specific configuration data from a variety of sources, making it a valuable tool for any PHP application. Depending on the source of the configuration data, different package libraries may be required to handle specific file formats or protocols.
