php分页接下来不行

Question

分页php，它不适用于下一个/预链接.... 预 下一个 要么 第一 持续 任何人都可以帮助我......

$perPage = 6;   // image count per page 

if (!isset($_GET['page'])) {
$pageId = $_GET['page'] = 1; }   // current page in url 

$offset = ($_GET['page'] - 1) * $perPage;
$userSet = $userModel->fetchPaginationServices($perPage, $offset, $services);


$pages = $userModel->servicesCount($services);
$totalPages = $pages / $perPage;



<div class="pagination">
<a href="">pre</a>
<?php
for ($i = 1; $i <= $totalPages; $i++) {
    echo "<a href='henna.php?page=$i'>$i</a>";
}
?>
<a href="">next</a>
</div>
