How can PHP developers ensure that header redirects are executed efficiently and effectively?

To ensure that header redirects are executed efficiently and effectively in PHP, developers should make sure that no output is sent to the browser before calling the header() function for the redirect. This can be achieved by placing the header() function at the top of the PHP script before any HTML or whitespace. Additionally, developers should use the "exit" or "die" function immediately after the header() function to stop the script execution and prevent any further code from being executed. 

<?php
// Place the header redirect at the top of the script
header("Location: http://www.example.com");

// Use exit or die to stop script execution
exit;
?>
