External link in menu

$uri = $menu['page_uri'];
			$external_link   = 'http';
			$pos = strpos($uri, $external_link);

			// Note our use of ===.  Simply == would not work as expected
			// because the position of 'a' was the 0th (first) character.
			if ($pos === false) {
			    echo anchor ("welcome/pages/".$menu['page_uri'], $menu['name']);
			} else {
			    echo anchor ($menu['page_uri'], $menu['name']);
			}
