What are some best practices for handling PHP fields in the frontend to ensure they are only displayed if they have been filled in the backend?

When working with PHP fields in the frontend, it is important to ensure that fields are only displayed if they have been filled in the backend. One way to achieve this is by using conditional statements in your frontend code to check if the PHP field has a value before displaying it. 

<?php
// Check if the PHP field has a value before displaying it
if (!empty($php_field)) {
    echo $php_field;
}
?>
