How can the PHP script be modified to ensure it enters the "nach submit" branch after form submission?

The PHP script can be modified by checking if the form has been submitted using the isset() function on the submit button's name. This ensures that the "nach submit" branch is entered after form submission. By adding this check, the script will only execute the code within the "nach submit" branch when the form has been submitted. 

<?php
if(isset($_POST['submit'])){
    // Form has been submitted
    echo "nach submit";
} else {
    // Form has not been submitted
    echo "vor submit";
}
?>
