 * I’m new to wordpress and php beginner and I’m learning how to debug the code.
   I’m building a widget and I want to see the value of a variable but I don’t know
   how cause echo and var_dump won’t output anything inside the widget.
 * add_filter(‘filter’, myCallBack);
 * function myCallBack($content){
    //here I would like to see the value of $content
   but var_dump($content); //nothing outputted echo $content; //nothing here either
   return $content }
 * Thanks in advance for the help.
