To keep curry leaves longer you can wash the sprigs, tie with a piece of string and hand it upside down, it remains green for long.
As for cilantro/dhania, you can just wrap it in a damp napkin and keep it in the vegetable box in the fridge, keep the cloth damp after 2/3 days, also do not wash the cilantro/dhania, only take out how much you need and then wash and chop it.
Another method is to put a whole egg in a plastic box (the icecream containers are ideal) and then put the coriander over it, make sure not to crack or break the egg, cover and keep in the fridge, this stays fresh for almost a week or more.
Hope you can try these with some success.
