* ``PMA_ABSOLUTE_URI`` - the full URL to phpMyAdmin. Sometimes needed when used in a reverse-proxy configuration. Don't set this unless needed. See [documentation](https://docs.phpmyadmin.net/en/latest/config.html#cfg_PmaAbsoluteUri).
* ``PMA_CONFIG_BASE64`` - if set, this option will override the default `config.inc.php` with the base64 decoded contents of the variable
