Are there alternative methods to achieve header updates without using meta refresh in PHP?

Using meta refresh for header updates is not recommended as it can cause issues with SEO and user experience. An alternative method to achieve header updates in PHP is by using the header() function to send a raw HTTP header to the client. This allows you to set the location header to redirect the user to a new page or update other headers as needed.

// Set the location header to redirect the user to a new page after a delay
header("Refresh: 5; url=newpage.php");

// Update other headers as needed
header("Cache-Control: no-cache, must-revalidate");
header("Expires: Sat, 26 Jul 1997 05:00:00 GMT");
