What are the differences between using <meta http-equiv="Refresh" content="5; url=http://example.com"> and PHP header("Refresh: 10; url=http://www.php.net") for redirecting after a certain time?

When redirecting a user to another page after a certain time, using the <meta http-equiv="Refresh" content="5; url=http://example.com"> meta tag in HTML will automatically redirect the user after 5 seconds, while using PHP header("Refresh: 10; url=http://www.php.net") will redirect the user after 10 seconds. The PHP header method gives more control and flexibility over the redirect time compared to the meta tag.

<?php
header("Refresh: 10; url=http://www.php.net");
exit;
?>
