How can conditional statements like isset or empty be used in PHP to display fields only if they are filled in the backend?

To display fields only if they are filled in the backend, you can use conditional statements like isset() or empty() in PHP. This allows you to check if a variable has been set or if it is empty before displaying it on the frontend. By using these conditional statements, you can ensure that only fields with data are displayed to the user, improving the user experience and preventing any empty or undefined fields from being shown. 

<?php
if(isset($variable1) && !empty($variable1)) {
    echo $variable1;
}

if(isset($variable2) && !empty($variable2)) {
    echo $variable2;
}
?>
