What best practices should be followed when using the header() function in PHP to redirect to a new page?

When using the header() function in PHP to redirect to a new page, it is important to follow best practices to ensure a smooth and secure redirection process. One key practice is to make sure that no output has been sent to the browser before calling the header() function, as headers must be sent before any actual content. Additionally, it is recommended to use the exit() function after the header() function to prevent any further execution of code. 

<?php
// Ensure no output has been sent
ob_start();

// Perform any necessary checks or validation

// Redirect to a new page
header("Location: newpage.php");

// Prevent any further execution
exit();
?>
