In PHP forms, you can make a field required by checking if the respective $_POST or $_GET variable is not empty. When the form is submitted, you can check if the value of the required field (accessed through the $_POST or $_GET superglobal) is not empty. If it is empty, it indicates that the required field was left blank by the user. This allows you to enforce the required field condition and handle it accordingly in your form handling logic.
