What are the differences between using header() and Meta-Tag for redirection in PHP?

Using header() function for redirection in PHP is a server-side redirection method that sends an HTTP header to the browser to redirect to a different page. On the other hand, using Meta-Tag for redirection is a client-side method that uses HTML meta tags to instruct the browser to automatically redirect to a different page after a specified time. Here is an example of using header() function for redirection in PHP:

<?php
// Redirect to a different page
header("Location: https://www.example.com");
exit;
?>
