Is MySQLnd Enabled?

Determining MySQLnd Driver Status

Verifying if MySQLnd is the active database driver is crucial when using MySQL with PHP. This advanced driver provides enhanced performance and functionality compared to the legacy driver.

Checking for MySQLnd Using MySQLi

For MySQLi connections, you can employ the following code to ascertain MySQLnd status:

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

if ($mysqlnd) {
    echo 'mysqlnd enabled!';
}</code>

Verifying MySQLnd with PDO

To determine MySQLnd status when using PDO, initialize your PDO object for MySQL and then evaluate the following:

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

Note: It's important to be aware that the above method may not be reliable and can cause discrepancies starting with PHP 8.1.
