wp-config.php

<?php
/**
 * WordPress Multi-Environment Config
 *
 * Loads config file based on current environment, environment can be set
 * in either the environment variable 'WP_ENVIRONMENT_TYPE' or can be set based on the
 * server hostname.
 *
 * This also overrides the option_home and option_siteurl settings in the
 * WordPress database to ensure site URLs are correct between environments.
 *
 * Common environment names are as follows, though you can use what you wish:
 *
 *   production
 *   staging
 *   development
 *
 * For each environment a config file must exist named wp-config.{environment}.php
 * with any settings specific to that environment. For example a development
 * environment would use the config file: wp-config.development.php
 *
 * Default settings that are common to all environments can exist in wp-config.default.php
