I'm not sure that question makes much sense. What do you want to use for the hash key and what will the values be (where do they each come from). The array only supplies one - the key or the value.

Perhaps you need to define your problem a little more? It may help to give a little sample data and show us the code that you have tried and are having problems with. It helps even more if you show us what your code prints and what you expected it to print.
