the search response return "nextpagetoken" , possibly "prevpagetoken" can passed next request (which, other changing page token, should identical current request) different set of data. pass "pagetoken" parameter (not part of url path code here). so, example, modify search request this:

$searchresponse = $youtube->search->listsearch('id,snippet', array(   'q' => $_get['q'],   'maxresults' => '10',   'pagetoken' => $_get['pagetoken'] ));

then, display search results, , below "next" link should modified this:

<h1><a href="<?php echo $_server['request_uri'] ?>?q=<?php echo $_get['q']>&pagetoken=<?php echo $searchresponse['nextpagetoken'] ?>">next</a></h1>
