How can JavaScript be integrated into PHP to achieve automatic page loading after a specific time interval?

To achieve automatic page loading after a specific time interval using JavaScript integrated into PHP, you can use the `header()` function in PHP to send a redirect header to the browser after a specified time. This redirect can point to the same page or a different page where the user should be redirected. 

<?php
// Set the time interval after which the page should automatically redirect (in seconds)
$timeInterval = 5;

// Send a redirect header to the browser after the specified time interval
header("Refresh: $timeInterval; url=redirect_page.php");

// Output a message to inform the user about the automatic redirect
echo "This page will automatically redirect in $timeInterval seconds. If not, click <a href='redirect_page.php'>here</a>.";
?>
