我怎么知道MySQLnd是否是活动驱动程序?

How can i know if it MySQLnd is the active driver?

我正在运行PHP 5.3和MySQL 5.1.37. 在phpinfo()中，列出了mysqlnd，但是只有这样，我不能确定我是在使用MySQLnd还是旧的驱动程序...

I'm runing PHP 5.3 and MySQL 5.1.37. In phpinfo() mysqlnd is listed but only with this I can't be sure if I'm using MySQLnd or the old driver...

提取phpinfo()输出

I'm using PDO, and PDO driver says mysql...

推荐答案

这应该可以解决问题:

<?php
$mysqlnd = function_exists('mysqli_fetch_all');

if ($mysqlnd) {
    echo 'mysqlnd enabled!';
}

要检测其是否为活动的PDO驱动程序，请创建您的MySQL PDO对象，然后:

To detect if its the active PDO driver, create your MySQL PDO object then:

if (strpos($pdo->getAttribute(PDO::ATTR_CLIENT_VERSION), 'mysqlnd') !== false) {
    echo 'PDO MySQLnd enabled!';
}
