Before outputting page content
Redirect based on the home URL
wp_redirect( home_url( '/' ) );
die;
wp_redirect( home_url( '/my_page_name' ) );
die;Redirect based on the site URL
wp_redirect( site_url() );
exit;If you’ve outputted some page content
Using a META tag is the easiest way
die('<META HTTP-EQUIV="refresh" content="0;URL=/some_page">');
