Zend 分页与数组
我目前正在使用 ezSQL，我相信它是一个很棒的 SQL 包装器。我的任务是添加我们可以直接插入的分页。Zend 有one，这似乎应该可以工作，因为它与 Zend 的其余部分松散耦合。我使用 ezSQL, ala: 返回一个数组，
$results = $db->get_results("SELECT * FROM table", ARRAY_A);
然后将其转移到分页器：
$paginator = Zend_Paginator::factory($results);
如果我 var_dump($paginator)，我会看到查询中列出的值。但是，如果我echo $paginator->pageCount)，我会得到NULL。这是怎么回事？
不幸的是，从 ezSQL 切换到 Zend_DB 对于我们组来说基本上是不可能的，所以这是不可能的。
编辑：print_r($paginator)的输出：

I'm currently using ezSQL, which I believe to be a great SQL wrapper. I've been tasked with adding in pagination that we can just drop in. Zend has one, which seems like it should work, as it's loosely coupled with the rest of Zend. I'm returning an array with ezSQL, ala:
$results = $db->get_results("SELECT * FROM table", ARRAY_A);
and then shifting this in to the paginator:
$paginator = Zend_Paginator::factory($results);
If I var_dump($paginator), I see the values listed from the query. However, if I echo $paginator->pageCount), I get NULL. What's the deal?
Unfortunately, switching from ezSQL to Zend_DB is essentially impossible for our group, so that's out of the question.
EDIT: Output from print_r($paginator):

正如 Zak 所写，您缺少
可以创建一个视图脚本来呈现分页器控件和分页器中的项目的功能。
则必须调用。
如果您不使用 Zend_View 及其 paginatorControl 视图助手，
As Zak wrote, you are missing
that you can create a view script to render the paginator controls and the items in the paginator.
Than you have to call
if you are not using Zend_View and it's paginatorControl view helper.
