// Retrieve value from configuration file $databaseConfig = require('config/database.php'); $host = getVar('host', $databaseConfig);
// Retrieve value from an array $config = [ 'debug' => true, 'version' => '1.0.0' ]; $debug = getVar('debug', $config);In this example, the getVar function is used to retrieve the 'debug' value from the array '$config'. The first parameter passed to getVar is the key to retrieve, and the second parameter is the array containing the configuration values. Package Library: This example does not specify a package library since it is a standard PHP function.
