How can the issue of browser caching affecting form input fields be addressed in PHP form submissions to ensure a consistent user experience?

Issue: Browser caching can cause previously entered form values to persist when a user navigates back to a form page, potentially leading to confusion or errors. To address this, we can add a unique identifier to the form action URL to ensure that the browser treats each submission as a separate request. PHP Code Snippet: 

<form method="post" action="<?php echo $_SERVER['PHP_SELF'].'?'.uniqid(); ?>">
  <!-- Form fields go here -->
</form>
