How do I know if I\'m using the MySQLnd driver in PHP?

Detecting Active MySQL Driver: MySQLnd or Legacy?

Determining Active Driver

Knowing whether the MySQLnd driver is active is crucial for ensuring optimal performance and compatibility with newer PHP and MySQL versions.

Checking via mysqli

To ascertain if MySQLnd is the active driver for mysqli connections, you can perform the following code check:

<code class="php"><?php
$mysqlnd = function_exists('mysqli_fetch_all');

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

Checking via PDO

To determine if MySQLnd is the active driver for PDO connections, create a MySQL PDO object and execute the following code:

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

Caution

Note that the method of detecting the active driver via phpinfo() is unreliable and should not be considered conclusive.
