How can the PHP script be modified to ensure that the meta tag for refresh is included in the HTML output?

To ensure that the meta tag for refresh is included in the HTML output, you can modify the PHP script to generate the meta tag dynamically and include it in the HTML header section. This can be achieved by using the header() function in PHP to set the refresh meta tag.

<?php
// Set the refresh time in seconds
$refresh_time = 5;

// Generate the meta tag for refresh
$refresh_meta = '<meta http-equiv="refresh" content="' . $refresh_time . '">';

// Output the HTML with the refresh meta tag
echo '<!DOCTYPE html>
<html>
<head>
<title>Page Title</title>
' . $refresh_meta . '
</head>
<body>
<p>This is a sample page content.</p>
</body>
</html>';
?>
