note 38182 added to function.require-once

When I use these code: define("RELATIVE_PATH", "./"); $strCommonFile = RELATIVE_PATH."includes/common.inc.php"; require_once($strCommonFile); I got this error message: Parse error: parse error, expecting `T_CONSTANT_ENCAPSED_STRING' in... But when I use: require_once("./includes/common.inc.php"); then everything work fine. Please, tell me why I got that error message!
