How to add my own error messages ?

[wahyusa]

Hi, thank you for this simple framework.. really easy to use!!

I'm try to build CRUD app, but I'd love to show some friendly messages instead of

Fatal error: Uncaught PDOException: ...

I've try to turn off development mode so it will not show the error message then I can just add error message (via ajax) based on HTTP status like code 500, but I think need something more easier and readable than this, maybe something like this

// err message with db connection/query
$db = new \Wolff\Core\DB('with incorrect database account');
if(!$db)
{ echo "my own friendly messages" }

$exec = $db->query('do something but error');
if(!$exec)
{ echo "my own friendly messages" }

is this possible ?
