Support » Everything else WordPress » VAriable value

  • 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.
