How can the use of form attributes like "form" and "formaction" be leveraged to streamline form handling and data processing in PHP applications?

Using form attributes like "form" and "formaction" can streamline form handling and data processing in PHP applications by allowing you to specify the form's action URL directly in the HTML form tag. This eliminates the need to manually set the form's action attribute in the PHP code, making the code cleaner and easier to maintain.

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