$title = isset( $instance['title'] ) ? $instance['title'] : '';
$title = strip_tags($instance['title']);
what is the difference between the above two?
Do they perform the one and the same action in the widget form method? Or I am mistaking something as they have different functions or one is used in widget form function and the another one is used in the widget’s widget method?
Or they just the difference of coding practice?
Or if they are performing the same action then we can combine them and make a better fusion like this →
$title = isset( $instance['title'] ) ? strip_tags($instance['title']) : '';
Please also help me to understand what is the role of this here →
