The site_url template tag retrieves the site url for the current site (where the WordPress core files reside) with the appropriate protocol, 'https' if is_ssl() and 'http' otherwise. If scheme is 'http' or 'https', is_ssl() is overridden. Use this to get the "WordPress address" as defined in general settings. Use home_url() to get the "site address" as defined in general settings.
In case of WordPress Network setup, use network_site_url() instead.
<?php site_url( $path, $scheme ); ?>
<?php echo site_url(); ?>
$url = site_url(); echo $url;
Output: http://www.example.com or http://www.example.com/wordpress
(Note the lack of a trailing slash)
$url = site_url( '/secrets/', 'https' ); echo $url;
Output: https://www.example.com/secrets/ or https://www.example.com/wordpress/secrets/
site_url() is located in wp-includes/link-template.php.
