    Since the method is a static, one practice is using it to check whether a specific server database driver is available and configured correctly with PDO before establishing the connection:
    <?php
    try {
    if (!    in_array("mysql",PDO::getAvailableDrivers(),TRUE))
    {
    throw new     PDOException ("Cannot work without a proper database setting up");
    }
    }
    catch (    PDOException $pdoEx)
    {
    echo     "Database Error .. Details :<br /> {$pdoEx->getMessage()}";
    }
    ?>
    or to check for any driver in general:
    <?php
    if (empty(PDO::getAvailableDrivers()))
    {
    throw new     PDOException ("PDO does not support any driver.");
    }
    ?>
