How can one modify PHP code to ensure proper functionality when using form actions?

When using form actions in PHP, it is important to properly handle form submissions to ensure the functionality works as intended. One way to do this is to check if the form has been submitted before processing the form data. This can be done by checking if the form submit button has been clicked using the isset() function in PHP. 

<?php
if(isset($_POST['submit'])){
    // Process form data here
    // For example, you can access form fields using $_POST['field_name']
}
?>
