You can create arrays from form elements using square brackets [].

<input type="hidden" name="billing[]" value="billing-info1">
<input type="hidden" name="billing[]" value="billing-info2">
<input type="hidden" name="billing[]" value="billing-info3">

(.. 0=>'billing-info1',1=>'billing-info2' ..).

, :

<input type="hidden" name="billing[key0]" value="billing-info1">
<input type="hidden" name="billing[key1]" value="billing-info2">
<input type="hidden" name="billing[key2]" value="billing-info3">

:

'key0' => 'billing-info1',
'key1' => 'billing-info2',
'key2' => 'billing-info3'
