verbose Exception, errors like in java. everything should be object

of course I use Xdebug, but when i have error in DB i do not get stacktrace . I am thinking about using http://getsparks.org/packages/tracer/versions/HEAD/show


I am using CI 2.1.0. Or you may recommend me some other solution. to have all verbose errrors.
for example T_PAAMAYIM_NEKUDOTAYIM
