What is the purpose of using the "form action" attribute in PHP?

The "form action" attribute in PHP is used to specify the URL of the file that will process the form data submitted by the user. It is essential for directing the form data to the correct PHP script for processing, such as storing in a database or sending an email.

<form action="process_form.php" method="post">
  <!-- Form fields go here -->
  <input type="submit" value="Submit">
</form>
