Why is it important to properly define the form action in HTML when working with PHP scripts?

It is important to properly define the form action in HTML when working with PHP scripts because the form action attribute specifies where the form data should be submitted to. If the form action is not correctly defined, the PHP script may not receive the form data or may send it to the wrong location. To ensure that the PHP script processes the form data correctly, the form action should point to the PHP script that will handle the form submission.

<form action="process_form.php" method="post">
  <!-- form fields go here -->
</form>
