I don't see the use of 2 parameters in this function

$random = array_rand($catalog, 4);
foreach($random as $id) {
   echo get_item_html($id, $catalog[$id]);
}

Why would we need the first parameter in that function if we've already used the value for $id on $catalog[$id], and we're not doing anything to first parameter alone, why is that?

function get_item_html($id, $item) {
  $output = '<li><a href="#"><img src="' 
      . $item['img'] . '" alt="' 
      . $item['title'] . '"/>' 
      . '<p>View Details</p>' 
      . '</a></li>';
  return $output;
}

As you see we don't use the first parameter here in any way, so why do we even need 2 parameters?
