What are the limitations of forcing browser caching through PHP headers and how can users bypass this caching?

Forcing browser caching through PHP headers can have limitations as users can bypass this caching by simply clearing their browser cache or using browser extensions that disable caching. To address this issue, you can implement versioning in the URLs of your static assets so that when the assets change, the URL changes as well, prompting the browser to fetch the updated asset.

<?php
$version = '1.0.0'; // Update this version number whenever your static assets change

// Example usage in HTML
echo '<link rel="stylesheet" type="text/css" href="styles.css?v=' . $version . '">';
echo '<script src="script.js?v=' . $version . '"></script>';
?>
