Actually, it's even easier than that. No need to specify the index when
you're using the default.
<input name='inp[]' type='hidden' value='first value'>
<input name='inp[]' type='hidden' value='second value'>
<input name='inp[]' type='hidden' value='third value'>
inp[0] == 'first value'
inp[1] == 'second value'
inp[2] == 'third value'
