What is the significance of the "nach submit" and "vor submit" branches in the PHP script?

The "nach submit" and "vor submit" branches in the PHP script are likely referring to actions that should occur after and before a form submission, respectively. These branches can be used to perform different tasks based on whether the form has been submitted or not. To implement this, you can check if the form has been submitted using the isset() function on the form submission variable ($_POST['submit']) and then execute the relevant code based on the condition. 

<?php
if(isset($_POST['submit'])) {
    // Code to execute after form submission (nach submit)
    // For example, process form data, save to database, or display success message
} else {
    // Code to execute before form submission (vor submit)
    // For example, display the form for user input
}
?>
