Question

这是我的疑问：

    $query = $db->prepare("

            EXPLAIN SELECT transaction.id, transaction.dateCreated, transaction.dateUpdated, transaction.brandId, transaction.clientId, transaction.serviceId, transaction.currencyCode, transaction.type, transaction.token, transaction.amount, transaction.reason, transaction.referenceOrderId, transaction.serviceTransactionId, transaction.chainMode, transaction.bonusCode, transaction.codeId, transaction.codeMessage, su.name AS user_name, su.surname AS user_surname, b.name AS brand_name, su.email_address, su.player_id, sandbox, integrationId 
            FROM transaction_AstroPay transaction
            LEFT JOIN tokens t ON transaction.token = t.token
            LEFT JOIN sys_users su ON su.id=t.user_id
            LEFT JOIN brands b ON b.api_brand_code = transaction.brandId
            WHERE transaction.clientId = :clientId


    ");
    $query->bindParam(':clientId',$clientId,PDO::PARAM_INT);
    $query->execute();  
    $result = $query->fetchAll(PDO::FETCH_ASSOC);

执行良好的查询，并从数据库中提取数据。我的问题是如何获得有关花费多少时间的详细信息。在mysqli EXPLAIN SELECT正在运作。

我们在mysqli中收集了这样的信息：

$sql = 'EXPLAIN SELECT * FROM table WHERE condition = "condition"';
$result = $mysqli->query($sql);
$row = $result->fetch_array(MYSQLI_NUM);
echo $row[0];

我如何在PDO中执行此操作？

PHP / PDO - PDO的EXPLAIN SELECT有可能吗？
