WordPress admin makes it easy to manage configurations without touching a line of code. These basic configuration settings are then stored in the wp-options table inside the database. But, WordPress also has a separate configuration file, called wp-config.php, that can be used for further customizations.
Wp-config is the file where your custom hosting data (database name, database host, etc.) is saved when you install a self-hosted WordPress site. You can also add other configuration options to this file, with which you can enable or disable features such as debugging, cache, multisite, SSL login, automatic updates, and many others.
