What are the limitations of using PHP for client-side reload in the browser?

When using PHP for client-side reload in the browser, one limitation is that PHP is a server-side language and cannot directly interact with the client-side browser. To overcome this limitation, you can use JavaScript to trigger a reload on the client-side.

// PHP code to redirect to a different page using JavaScript for client-side reload
echo '<script>window.location.href = "newpage.php";</script>';
