Update Plugin's config.php Is it possible to update the config.php file in a plugin outside of manually opening and adjusting the array? I'm hoping there's a way I can have a certain user group be able to change the array values with the plugin's control panel page.

The config file is very simple, it looks like this:

&lt;?php 

return [

    'active_features' =&gt; [
         'change_team' =&gt; false,
         'change_series' =&gt; false,
         'change_user_settings' =&gt; false,
    ],

];


And I need a way for them to be able to toggle, say, 'change_team' to true or false every so often. I've searched around and haven't found anything at all to try. Does this kind of functionality exist at all?
In this situation you don't want to use a config file and instead you want to use plugin settings. The settings have a UI and save to the db, which does exactly what you want. The config files are meant to only be updated manually updating them.
