按键的多维数组的和值

Question

I have this multi dimensional array

I want to sum the values of cost and get the average of cpm every campaign id and I only get the last part of the array.

This is my code

while (strtotime($startDate) <= strtotime($endDate)) {
    $newStartDate = date ("Y-m-d", strtotime("+1 day", strtotime($startDate)));

    $params = array(
        'date'=> $newStartDate
    );
    $reports = $client->__soapCall('getDailyTargetsStats', array($params));

    $dateToday = date('Y-m-d');
    $cost = 0;
    $resultArray = $reports->stats->item;
    foreach ($resultArray as $value) {
        $campaignId = $value->campaignId;
        $cost += $value->cost;

        if ((!$newStartDate) || (!$campaignId)) {
            continue;
        }
        //get campaign names
        $campaignName =  $this->get_campaigns($campaignId);

        $data = array(
            'date' => $newStartDate,
            'campaign_id' => $campaignId,
            'campaign_name' => $campaignName,
            'cost' => $cost
        );
        echo '<pre>';
        var_dump($data);
        echo '</pre>';
        exit;   
    }
    sleep(5);
    $startDate = $newStartDate;
}

Any suggestions will do, I am currently developing it in CodeIgniter and PHP 5.6.

Then current code now is this

foreach ($resultArray as $value) {
                $campaignId = $value->campaignId;
                $cost += $value->cost;

                if ((!$newStartDate) || (!$campaignId)) {
                    continue;
                }

                //get campaign names
                $campaignName =  $this->get_campaigns($campaignId);

                $data = array(
                    'date' => $newStartDate,
                    'campaign_id' => $campaignId,
                    'campaign_name' => $campaignName,
                    'cost' => $cost
                );



            }
            echo '<pre>';
            var_dump($data);
            echo '</pre>';
            exit;

This may work for you:

foreach ($resultArray as $value) {
    $campaignId = $value->campaignId;
    $newStartDate = $value->newStartDate;

    if ((!$newStartDate) || (!$campaignId)) {
        continue;
    }

    $cost = $value->cost;

    //get campaign names
    $campaignName = $this->get_campaigns($campaignId);

    $data[campaign_id] = array(
        'date' => $newStartDate,
        'campaign_id' => $campaignId,
        'campaign_name' => $campaignName,
        'cost' => $data['campaign_name'] + $cost
    );
}
