Confirming MySQLnd as the Active Driver

While the presence of MySQLnd in phpinfo() indicates its installation, it does not guarantee that it is the active driver. To definitively determine whether MySQLnd is operational, additional measures are necessary.

Checking for MySQLnd in mysqli

To ascertain MySQLnd's status in mysqli, you can utilize the mysqli_fetch_all function. The presence of this function signifies that MySQLnd is enabled:

$mysqlnd = function_exists('mysqli_fetch_all');

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

Verifying MySQLnd for PDO

To confirm MySQLnd's active status in PDO, follow these steps:

1. Establish a MySQL PDO object.
2. Utilize the getAttribute(PDO::ATTR_CLIENT_VERSION) method to retrieve the client API version.
3. Search for the string 'mysqlnd' within the retrieved version. If it is present, MySQLnd is the active PDO driver:

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