The latter.  But note, if a box isn't checked, it's not going to be 
sent, so won't be in the array.

   <input type="checkbox" name="StateID[]" value="32" /> NV
   <input type="checkbox" name="StateID[]" value="33" checked /> NH
   <input type="checkbox" name="StateID[]" value="34" checked /> NJ

In this case $_POST['checkbox'][0] would be 33 and ...[1] would be 34.

Sometimes it's handy to identify the key upfront:

   <input type="checkbox" name="StateID[32]" value="608" /> NV
   <input type="checkbox" name="StateID[33]" value="2" /> NH
   <input type="checkbox" name="StateID[34]" value="40" checked /> NJ

That would yield $_POST['checkbox']['34'] = 40.

A nice way to handle incomming checkboxes is this:

   while ( list($Key, $Val) = each($checkbox) ) {
      #  do what you need to do...
      #  for example, show what was sent...
      echo "<br />$Key = $Val\n";
