note 20639 modified in function.setcookie by john

If you already have a variable set with the same name you are about to assign a cookie to, the cookie will not set AND you will not get an error message. For example, if you have a login box that has an input field called "username," post that value to a user authentication page and then set a cookie called "username" the cookie won't set. Use different names and you are back in action. [Editor's Note: This should only apply if register_globals is on. Otherwise, the cookie should be available in in the superglobal array $_COOKIE] --was-- If you already have a variable set with the same name you are about to assign a cookie to, the cookie will not set AND you will not get an error message.
