you use them not for control flow, but for deferring exceptional application
states, which you can then handle in a small number of places as opposed
to scattering the error handling of unlikely events in all sorts of
disparate places.
there is an art to using them, they compliment 'traditional' error handling,
and I agree they can hinder if used badly.
NB: you can have multiple catch blocks:
try {
// do lots of stuff
} catch (ConnectException $e) {
} catch (QueryException $e) {
} catch (DBSelectException $e) {
} catch (Exception $e) {
// catch all for stuff we don't handle specifically
}
