PHP does magic if you name the input B[], I think, so that it makes all values available via B as an array. Another approach (eg that taken by Django) is to provide a "multi-map", so that you can get all the values out whatever the input name.

Strictly, the browser doesn't send an array ever; it just sends a number of name-value pairs, and each name can appear multiple times. How the backend system copes with this varies, as Richard points out. This stuff is pretty obscure unless you've done it in detail before though :)
