note 27140 added to function.parse-url

While this sounds completely trivial, I looked around to no avail... how does one return the complete url of the current page (ie. http://www.php.net/manual/en/function.parse-url.php for the current page ;) in order to parse that url and extract, for instance, the scheme? Or is there another / better, more direct way to return the scheme of the current page? -- http://www.php.net/manual/en/function.parse-url.php http://master.php.net/manage/user-notes.php?action=edit+27140 http://master.php.net/manage/user-notes.php?action=delete+27140 http://master.php.net/manage/user-notes.php?action=reject+27140
