How can the use of header() function in PHP impact the redirection process within a script?

The use of the header() function in PHP can impact the redirection process within a script by sending an HTTP header to the browser, instructing it to redirect to a different location. This can be useful for redirecting users to another page after a form submission or to handle authentication. To implement a redirection using the header() function, you need to ensure that no output has been sent to the browser before calling the function, as headers must be sent before any actual content. Additionally, you should use the "Location" header to specify the URL to redirect to. 

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