How important is it to clear the browser cache after making changes to PHP scripts, and what impact can it have on the display of the website?

It is important to clear the browser cache after making changes to PHP scripts because the browser may still be using the old cached version of the script, leading to display issues or errors on the website. Clearing the cache ensures that the browser fetches the updated version of the script and displays the website correctly. 

<?php
// Add a version parameter to the script URLs to force the browser to fetch the updated version
$version = time();
echo '<script src="script.js?v=' . $version . '"></script>';
echo '<link rel="stylesheet" href="styles.css?v=' . $version . '">';
?>
