Zend framework2 ZEND此结果是仅向前的结果集，不支持在向前移动后调用rewind（）

我在此代码后出现此错误：

此结果是仅向前的结果集，不支持在向前移动后调用rewind（）

Page.phtml：

foreach ($company as $key => $value) 
                        {

companyTable.php

    return $resultSet ;
}

为什么我没有权利嵌入我的两个“foreach（）”？

您需要缓冲结果

public function fetchAll()
{
    $resultSet = $this->tableGateway->select();
    $resultSet->buffer();

    return $resultSet ;
}
