How can PHP code be optimized to ensure proper execution of redirection without interfering with other processes?

To optimize PHP code for proper redirection without interfering with other processes, it is important to use the header() function before any output is sent to the browser. This ensures that the redirection headers are sent before any content, preventing any conflicts with other processes. Additionally, using exit() or die() after the header() function can help terminate the script immediately after redirection.

<?php
header("Location: https://www.example.com");
exit();
?>
