mysql - ZF2 での mysql クエリからの結果の取得

Question

これが私のモデルです：

<?php

namespace Object\Model;

use Zend\Db\TableGateway\TableGateway;
use Zend\Db\Sql\Sql;

class SiteVisitsTable {

protected $tableGateway;
protected $sql;

public function __construct(TableGateway $tableGateway) {
    $this->tableGateway = $tableGateway;
    $this->sql = new Sql($this->tableGateway->adapter);
}

public function getVisits($field = '', $value = '') {
    if ($field = '' || $value = ''):
        $rowset = $this->tableGateway->select(array($field => $value));
    else:
        $rowset = $this->tableGateway->select();
    endif;

    $row = $rowset->current();
    return $row;
}

public function getAllVisits() {
    $adapter = $this->tableGateway->adapter;

    $select = $this->sql->select();
    $select->from($this->tableGateway->getTable());
    $select->columns(array(
        new \Zend\Db\Sql\Expression('SUM(`unique`) as `unique`'),
        new \Zend\Db\Sql\Expression('SUM(`impressions`) as `impressions`'),
    ));

    $selectString = $this->sql->getSqlStringForSqlObject($select);
    $resultSet = $adapter->query($selectString, $adapter::QUERY_MODE_EXECUTE);

    return $resultSet;
}

public function addVisit($date) {
    $currentVisits = $this->getVisits('date', $date);
    if ($currentVisits) {
        $data = array(
            'unique' => $currentVisits + 1,
        );

        $this->tableGateway->update($data, array('date' => $date));
    } else {
        $data = array(
            'unique' => 1,
            'impressions' => 1,
        );

        $this->tableGateway->insert($data);
    }
}
}

getAllVisits public メソッドには、SELECT CUM MySQL クエリがあります。クエリ自体はすべて問題ありませんが、クエリから値を出力できません。$resultSet のダンプは次のとおりです。

Zend\Db\ResultSet\ResultSet Object
(
[allowedReturnTypes:protected] => Array
    (
        [0] => arrayobject
        [1] => array
    )

[arrayObjectPrototype:protected] => ArrayObject Object
    (
        [storage:ArrayObject:private] => Array
            (
            )

    )

[returnType:protected] => arrayobject
[buffer:protected] => 
[count:protected] => 1
[dataSource:protected] => Zend\Db\Adapter\Driver\Pdo\Result Object
    (
        [statementMode:protected] => forward
        [resource:protected] => PDOStatement Object
            (
                [queryString] => SELECT SUM(`unique`) as `unique`, SUM(`impressions`) as `impressions` FROM `site_visits`
            )

        [options:protected] => 
        [currentComplete:protected] => 
        [currentData:protected] => 
        [position:protected] => -1
        [generatedValue:protected] => 0
        [rowCount:protected] => 1
    )

[fieldCount:protected] => 2
[position:protected] => 
)

queryString キーが表示される場合があります。phpmyadmin で「生の」クエリを実行すると、MySQL データベースの値が表示されますが、ZF2 で表示しようとしても機能しないようです。

これが私のコントローラーです：

    return new ViewModel(array(
                'todayVisits' => $this->getSiteVisitsTable()->getVisits('date', date('Y-m-d')),
                'allVisits' => $this->getSiteVisitsTable()->getAllVisits(),
                'yesterdayVisits' => $this->getSiteVisitsTable()->getVisits('date', ''),
                'inactiveBlogs' => $this->getBlogsTable()->getInactiveBlogs(),
                'inactiveUsers' => $this->getUsersTable()->getUsers('is_active', '0'),
                'notes' => $this->getAdminNotesTable()->getAllNotes(),
                'form' => $form,
            ));

そして私の見解：

<article class="stats_overview">
<div class="overview_today">
    <p class="overview_day">Днес</p>
    <p class="overview_count"><?php echo $todayVisits->unique; ?></p>
    <p class="overview_type">посещения</p>
    <p class="overview_count"><?php echo $todayVisits->impressions; ?></p>
    <p class="overview_type">импресии</p>
</div>
<div class="overview_previous">
    <p class="overview_day">Общо</p>
    <p class="overview_count"><?php echo $allVisits->unique; ?></p>
    <p class="overview_type">посещения</p>
    <p class="overview_count"><?php echo $allVisits->impressions; ?></p>
    <p class="overview_type">импресии</p>
</div>
</article>

PS JOIN クエリにも同じ問題があります。：） 前もって感謝します。
