The general solution to your question is to store multiple values in an array that share a single key.

So instead of having Anand => 'xyz', you would have Anand => [ 'xyz', 'wer', 'ert', 'rew', 'tre' ]. Write some code and see how far you get, and we'll be glad to help you if you run into problems. We won't write the code for you.
