Php 与Zend_Paginator混淆

我真的很困惑Zend_Paginator是如何工作的

$dbProducts = $this->_table->fetchAll($this->_table->select());
//$dbProducts = new Zend_Paginator(new Zend_Paginator_Adapter_DbTableSelect($this->_table->select()));
//$dbProducts->setItemCountPerPage(4);
//$dbProducts->setCurrentPageNumber(1);

计数（$dbProducts）返回27

//$dbProducts = $this->_table->fetchAll($this->_table->select());
$dbProducts = new Zend_Paginator(new Zend_Paginator_Adapter_DbTableSelect($this->_table->select()));
//$dbProducts->setItemCountPerPage(4);
//$dbProducts->setCurrentPageNumber(1);

count（$dbProducts）返回3

//$dbProducts = $this->_table->fetchAll($this->_table->select());
$dbProducts = new Zend_Paginator(new Zend_Paginator_Adapter_DbTableSelect($this->_table->select()));
$dbProducts->setItemCountPerPage(4);
$dbProducts->setCurrentPageNumber(1);

count（$dbProducts）返回7…

对于Zend分页，有一个简单的示例。这是非常简单的集成，尝试一下

读过之后，试试这个

        $page = $this->_getParam('page', 1);
        $paginator = Zend_Paginator::factory($dbProducts);
        $paginator->setItemCountPerPage(20);
        $paginator->setCurrentPageNumber($page);

        $this->view->records = $paginator;
