//===============MY EXAMPLES - USAGE============//
(i.e. wordpress is installed in subdirectory:  http://example.com/wpdir/)

define('domainURL',                 (((!empty($_SERVER['HTTPS']) && $_SERVER['HTTPS']!=='off') || $_SERVER['SERVER_PORT']==443) ? 'https://':'http://' ).$_SERVER['HTTP_HOST']);
    // ----->  http://example.com
define('homeURL',                   home_url());
    // ----->  http://example.com/wpdir/
define('homeFOLD',                  str_replace(domainURL,'',   homeURL));
    // ----->                    /wpdir/
define('requestURI',                $_SERVER["REQUEST_URI"]);
    // ----->                    /wpdir/any-page?with=parameters
define('requestURIfromHome',        str_replace(homeFOLD, '',requestURI) );
    // ----->                          /any-page?with=parameters
define('requestURIWithoutParametr',parse_url(requestURIfromHome, PHP_URL_PATH));
    // ----->                    /wpdir/any-page
define('currentURL',                domainURL.requestURI);
    // -----> http://example.com/wpdir/any-page?with=parameters
define('THEME_URL',                 str_replace(domainURL, '', get_template_directory_uri()) );plugin_dir_url(__FILE__)) ); 
    // -----> http://example.com/wpdir/wp-content/themes/THE-THEME-NAME/
define('PLUGIN_URL',                str_replace(domainURL, '', plugin_dir_url(__FILE__)) ); 
    // -----> http://example.com/wpdir/wp-content/plugins/THE-PLUGIN-NAME/

Solution 1

$complete_url = "http://$_SERVER[HTTP_HOST]$_SERVER[REQUEST_URI]";

Solution 2 

$complete_url = (isset($_SERVER['HTTPS']) ? 'https://' : 'http://').$_SERVER['SERVER_NAME'].str_replace($_SERVER['DOCUMENT_ROOT'], '', dirname(dirname(__FILE__)));
