You’ll be able to confirm various variables of PHP as well as receive the notifications, warnings and fatal errors on WordPress by using this plugin. 
Usually WordPress users have to turn on the “WP_DEBUG” setting for debugging, but edump will show the information without needing it to be turned on, so you can recognize various notifications, warnings and errors on your production stage of WordPress. You can resolve and detect some issues easily by using this plugin.
