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.");
}
?>
