MySQLi connection with variables in config.php

I am creating a database connection class, that will access the variables or constants defined in the config.php. However, if I am going to create a theme and a plugin engine, how would I only allow the MySQLi connection class to access the config without allowing plugins/themes accessing the information breaching the security of the website & users.

Previously, I just defined host, username, password, and database as constants in the config, then included the config inside a file that included all of the core website files, such as the core functions file, database connection, etc - I believe this is how popular CMS's such as Wordpress, etc, does it? If not please correct me.

If I include the config inside the database class, but then include the database class inside the website, the config can be accessed by custom code inside the themes and plugins - which MUST NOT happen.

How would I go about doing this? I cannot think of any other way.

Thanks, Kieron

You don't. Instead you should give your MySQLi wrapper class all the settings it needs. ie:

class MySQLiWrapper {
    public function __construct($server, $username, $password, $database) {..}
}

As for internal security. PHP code has no sandboxing, any script can do an fopen on any file and read it's contents. Think about how you want to approach security.
