php - ZF2 分页器不显示最后一页

Question

我有 6 条查询记录，此代码在 3 个页面上正确显示:

(action)
    public function listAction()
        {
            $page  = (int) $this->params()->fromRoute('id', 0);
            $posts = $this->getPagesTable()->selectPages();
            $paginator = new Paginator(new PaginatorIterator($posts));
            $paginator->setCurrentPageNumber($page)
                      ->setItemCountPerPage(2)
                      ->setPageRange(7);
            return new ViewModel(array(
                    'paginator' => $paginator,
                    ));
        }
(view)
    <?php foreach ($paginator as $post) : ?>
         <h2><?php echo $this->escapeHtml($post->id); ?></h2>
         <div><?php echo $this->escapeHtml($post->name);?>
     <?php endforeach; ?>

但是当我添加 foreach 循环时:

public function listAction()
{
    $page  = (int) $this->params()->fromRoute('id', 0);
    $posts = $this->getPagesTable()->selectPages();
    $paginator = new Paginator(new PaginatorIterator($posts));
    $paginator->setCurrentPageNumber($page)
              ->setItemCountPerPage(2)
              ->setPageRange(7);
    foreach ($paginator as $post) {
        // some code or  empty foreach
    };
    return new ViewModel(array(
            'paginator' => $paginator,
            ));
}

分页器不显示最后 (3) 页(第 1 和 2 页正确显示)。 为什么？ 谢谢!

如果在foreach {}之后添加$paginator->getIterator()->rewind()，paginator只显示第一页，不显示第二页和第三页。

迭代器模式就像一个指针，在你迭代之后你必须重新设置它。
