Help Adding URLs to Tab Script

I've been working with this canned script and I cann't figure out where the add the destination URLs. Can anyone tell me how to add them?

<?

// add the class
require_once("paypaltabs.class.php");

// the item var will determine which tab is raised

if($HTTP_GET_VARS[item] == "") $item = 'Yahoo';
else $item = $HTTP_GET_VARS[item];

/*
// Create an array of tab items with urls, then declare the tabs 
// class and add the array with an image url for the tab images.
// Keep in mind the items are case sensitive.
*/

$tabs_items  = array(	'Google'=>$PHP_SELF.'?item=Google',
				'Yahoo'=>$PHP_SELF.'?item=Yahoo',
				'Dmoz'=>$PHP_SELF.'?item=Dmoz',
				'Dogpile'=>$PHP_SELF.'?item=Dogpile'

);

// specify the location of the images to be used

$tab_images_url = "/images";

$tabs = new PayPalTabs($tabs_items,$tab_images_url);

$tabs->ShowTabs($item);


?>

Code (markup):

thx,

 

I think this one is the array of links:

$tabs_items  = array(	'Google'=>$PHP_SELF.'?item=Google',
				'Yahoo'=>$PHP_SELF.'?item=Yahoo',
				'Dmoz'=>$PHP_SELF.'?item=Dmoz',
				'Dogpile'=>$PHP_SELF.'?item=Dogpile'

);

PHP:

you just do:

$tabs_items  = array(	'Google'=>'google.com',
				'Yahoo'=>'...',
				'Dmoz'=>'...',
				'Dogpile'=>'...'

);

PHP:
