Show all options (setting) in WordPress

Just navigate to this URL when logged in and you will get all settings.

/wp-admin/options.php

You can do it also little programming:

function all_settings_link() {
add_options_page(__('All Settings'), __('All Settings'), 'administrator', 'options.php');
}

add_action('admin_menu', 'all_settings_link');

It will add an additional option to your settings menu with a link to “all settings” which will show you a complete list of all the settings you have within your database related to your WordPress site.

The code will only work for an admin user.
