Function Reference/wp redirect

Redirects the user to a specified absolute URI.

wp_redirect() does not exit automatically and should almost always be followed by exit.

<?php
wp_redirect( $location, $status );
exit;
?>

$location

(string) (required) The absolute URI which the user will be redirected to.

Default: None

$status

(integer) (optional) The status code to use.

Default: 302

<?php wp_redirect( home_url() ); exit; ?>

Redirects can also be external, and/or use a "Moved Permanently" code :

<?php wp_redirect( 'http://www.example.com', 301 ); exit; ?>

The HTTP/1.1 status code 302 is a temporary redirect. If the page has moved permanently, use the HTTP status code 301.

wp_redirect() is located in wp-includes/pluggable.php.
