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.");
    }
?>

function getDriverList($ayrac = ",", $echo = true){

$ARR_DRIVERS = array();
$CountDrivers = 0;
foreach(PDO::getAvailableDrivers() AS $DRIVERS) :
     
    $CountDrivers++;
    $ARR_DRIVERS[$CountDrivers] = $DRIVERS;

endforeach;

$_GET_DRIVER_LIST = implode($ayrac, $ARR_DRIVERS);

if( $echo ): echo $_GET_DRIVER_LIST; else : return $_GET_DRIVER_LIST; endif;

}

Example :

echo "Kullanabileceğiniz pdo veritabanları : " . getDriverList(" , ", false);
