What’s the best and most intuitive way to have a user enter a height value in feet and inches into a web form?

What's the best and most intuitive way to have a user enter a height value in feet and inches into a web form? The major choices seem to be:

1. Have one text field where they can enter values. This becomes a moderately complex parsing problem if more than one or two formats are allowed, but it's doable.
2. Have two text fields, one for feet and one for inches.
3. Have two dropdowns, one for feet and one for inches. This disallows fractional inch values, though, unless there are lots of options in the inches dropdown.

I suppose this question also concerns entering any data item that is often seen as multi-part (phone numbers).
