Youtube API - Video Comments Pagination - php

Question

I'm using the following PHP code to get the comments for a specific video:
<?php
$vid = "G0k3kHtyoqc";
$feedURL = 'http://gdata.youtube.com/feeds/api/videos/' . $vid;
$entry = simplexml_load_file($feedURL);
$gd = $entry->children('http://schemas.google.com/g/2005');
if($gd->comments->feedLink){
$attrs = $gd->comments->feedLink->attributes();
$commentsURL = $attrs['href'];
$commentsCount = $attrs['countHint'];
}
if($commentsURL && $commentsCount > 0){
$commentsFeed = simplexml_load_file($commentsURL);
echo "<ol>";
foreach($commentsFeed->entry as $comment){
echo "<li>";
echo "<a target='_blank' href='http://www.youtube.com/user/" . $comment->author->name . "'>";
echo $comment->author->name;
echo "</a>";
echo " - " . $comment->content;
echo "</li>";
}
echo "</ol>";
}
?>
The problem with the code above is that it only gets the most recent 24 comments. I need a way to paginate through all comments.
Your help is much appreciated.
Thanks

Use the "start-index" param. Begins on 1, and depending on the comments count, add [comments-count] to start-index param.
For example:
First page of comments, getting 25 comments per page, use max-results=25 and start-index=1
Second page of comments, getting 25 comments per page, use max-results=25 and start-index=26
And so on =)
