the cookie can be accessed like any other variable in php. You can reference it by the name that you gave it. Thus if you named your cookie, \"cookie1\" you can access it by calling $cookie1. To access values stored in the cookie you must treat it as an array. You can use the following code to explode the cookie into array elements:
$displayResults = unserialize( stripslashes( $cookie_name ));
$cookieValue1 = $displayResults[0];
$displayResults[0] would be php_php in this case.
hope this helps.
