Answer 1

Name the inputs with square brackets at the end of their name. If there is no value inside the brackets, they will be put sequentially into an array. If there is a value, that will be used as the key in the array:

HTML:

<input type="hidden" name="inp[]" value="a" />
<input type="hidden" name="inp[]" value="b" />
<input type="hidden" name="inp[]" value="c" />
<input type="hidden" name="inp[foo]" value="bar" />

PHP:

print_r($_POST);
/* 
array(
    0 => 'a',
    1 => 'b',
    2 => 'c',
    'foo' => 'bar'
)
*/

The same should apply to the $_FILES array.
