How can PHP users effectively use the header function to navigate to other pages?

To navigate to other pages using the header function in PHP, users can specify the location they want to redirect to in the function call. This can be achieved by setting the "Location" header with the desired URL. It is important to make sure that no output is sent to the browser before using the header function to avoid any errors.

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