A good approach I've used in the past is to have two arrays for error
message; one for developers and one for users. Then you can do
something more like this:

try
{
// to add a record
}

catch(Exception $e) // but failed, because you can't add record again
some column is uniq.
{
$dev_error['db'] = $e->getMessage();
$user_error['db'] = "I'm sorry, that user name is already taken.
Please try again.";

}

That way in your debugging output you can see exactly what went wrong
and at the same time you can have a more friendly message for end
users, and without giving away too many details.
