Any <code>WPENV_</code> prefixed variables in the <code>.env</code> will be used to override the WordPress options. For example, if you’d like to set a specific environment to “Discourage search engines from indexing this site”, you can add <code>WPENV_BLOG_PUBLIC=0</code> to your <code>.env</code> file.
<ul>
<li>
Any option in the <code>wp_options</code> table or retrieved by <code>get_option()</code> can be set this way.
</li>
<li>
You can define keys either as <code>WPENV_BLOGDESCRIPTION</code> or as <code>WPENV_blogdescription</code>, both will work.
</li>
<li>
If you’d like to define the location of your <code>.env</code> file, rather than the plugin looking for it, you can filter <code>dotenv_location</code> to be a directory path.
</li>
<li>
You can also change the <code>WPENV_</code> prefix by filtering <code>dotev_key_prefix</code> to be a different prefix.
</li>
</ul>

Configurator is a plugin that allows you to edit the <code>wp-config.php</code> file of your installation within the browser.
It lists every item in your <code>wp-config.php</code> file and displays it as a form so you can edit them as you wish. Just be wary though, making a mistake on crucial parts, such as your database user and password, can allow you to crash your WordPress installation.
If at any point your WordPress stops working after editing your <code>wp-config.php</code> through Configurator, fear not! Configurator makes sure to back up your <code>wp-config.php</code> file before overwriting it, so that in the event that anything happens, you can simple delete your <code>wp-config.php</code> file and then rename <code>wp-config.php.bak</code> to <code>wp-config.php</code>!

Configurator is tested to work from 3.0. I am not aware of any incompatibilities so far.
