Here is my code:

$query =
        "SELECT click_view.gclid,click_view.keyword_info.text,ad_group.id,ad_group.name,"
        ."campaign.id,campaign.name,segments.click_type,segments.date "
        . "FROM click_view "
        . "WHERE segments.date DURING TODAY and click_view.gclid = '$gclid' "
        . "LIMIT 5";
    $stream = $googleAdsServiceClient->searchStream(
        123456789,
        $query
    );

    foreach ($stream->iterateAllElements() as $googleAdsRow) {

        $campaign = $googleAdsRow->getCampaign();
        $adGroup = $googleAdsRow->getAdGroup();
        $adGroupCriterion = $googleAdsRow->getAdGroupCriterion();
        $metrics = $googleAdsRow->getMetrics();
        $click_view=$googleAdsRow->getClickView();

        printf(
            "Keyword text '%s' with \n"
            . "Gclid %s  \n"
             ."AD Group Name - '%s' \n"
            . "AD Group ID - %d \n"
            . "Campaign Name  '%s' \n",
            $click_view->getKeyword()->getText(),
            $click_view->getGclid(),
            $adGroup->getName(),
            $adGroup->getId(),
            $campaign->getName(),
            PHP_EOL
        );
