How can PHP beginners effectively check if a database field is empty before outputting it on a webpage?

To check if a database field is empty before outputting it on a webpage, PHP beginners can use the isset() function to determine if the field has a value. By checking if the field is set and not empty, you can ensure that only non-empty values are displayed on the webpage. 

// Assuming $row is the array containing database results
if(isset($row['field']) && !empty($row['field'])) {
    echo $row['field'];
} else {
    echo "Field is empty";
}
