I would like to make an adress book app. I got the skills to achieve this goal in PHP. However I have a problem.

I have no idea about how to let user add multiple phone numbers, addresses, emails etc just like in today's mobile phones. How can I do this? I mean, how shall I design the DB in order to achieve this? Arrays? Or another table to store these datas and get the record count when showing phone number boxes etc?

What would you suggest?

Thank you very much for your ideas, highly appriciated.
