yes that is what I want to do.

I would like to do my paging like this site does

PEAR::Pager doesn't provide what you want to do
out-of-the-box, but you can do it this way
(please note that I've used the _getLinksUrl()
private method to get a clean url, so use it
at your own risk...):

========================================
=======
<?php
require_once 'Pager/Pager.php';

//create dummy array of data
$myData = array();
for ($i=0; $i < 200; $i++) {
$myData[] = $i;
}

$params = array(
'itemData' => $myData,
);

$pager = & Pager::factory($params);
$page_data = $pager->getPageData();

$prevPageGroupLink = '';
$nextPageGroupLink = '';

$pageRange = $pager->getPageRangeByPageId();
if ($pageRange[1] < $pager->numPages()) {
$nextPageGroupUrl = $pager->_getLinksUrl() . ($pageRange[1] + 1);
$nextPageGroupLink = '<a
href="'.$nextPageGroupUrl.'">»»</a>';
}
if ($pageRange[0] > 1) {
$prevPageGroupUrl = $pager->_getLinksUrl() . ($pageRange[0] - 1);
$prevPageGroupLink = '<a
href="'.$prevPageGroupUrl.'">««</a>';
}

$links = $pager->getLinks();

echo $links['first']
. ' '
. $prevPageGroupLink
. ' '
. $links['pages']
. ' '
. $nextPageGroupLink
. ' '
. $links['last'];
?>
========================================
=======

Alternatively, you can get the whole set
of links for the next "group" in this way:

========================================
=======
$nextGroup = '';
$pageRange = $pager->getPageRangeByPageId();
if ($pageRange[1] < $pager->numPages()) {
$links2 = $pager->getLinks($pageRange[1] + 1);
$nextGroup = $links2['pages']; //or $links2['all'];
}
echo $nextGroup;
========================================
=======

HTH
