How can special characters like "&" be properly handled in PHP form actions?

Special characters like "&" in form actions can be properly handled by using the PHP function urlencode() to encode the special characters before submitting the form data. This ensures that the special characters are properly interpreted by the server and prevents any issues with the form submission. 

<form action="submit.php?action=<?php echo urlencode('special&characters'); ?>" method="post">
    <!-- form fields here -->
</form>
