How can the header function be used effectively for redirection within the same server in PHP?

When using the header function for redirection within the same server in PHP, it is important to ensure that there is no output sent to the browser before the header function is called. This is because the header function sends an HTTP header to the browser, so any output before it will cause an error. To effectively use the header function for redirection, make sure to call it before any output is sent. 

<?php
// Make sure no output is sent before calling the header function
ob_start();

// Perform any necessary checks or processing

// Redirect to a new page within the same server
header("Location: new_page.php");
exit();
?>
