Why do we need $id as the first argument in echo get_item_html($id, $catalog[$id])?

It seems that we are not really utilising $id later on in function get_item_html($id, $item)

it is not simply using it, needs only $catalog[$id] to get desired output.

I have tried removing $id as arguments from both functions and everything worked fine. Can someone explain, why we need it? <?php

function get_item_html( $item){/we really need only $item = $catalog[$id] to get output, I do not see how function utilise $id itself/

     $output = "<li><a href = '#'><img src = '"
      .$item["img"] . "' alt = '"//search for desired property and adds their locations
      .$item["title"] ."'/>" . 
      "<p>View detaiils</p>" .
      "</a></li>";

      return $output;
     }

$categories= array_category($catalog,$section); foreach($categories as $id ){/generating random catalog id, outputs [0]=>int(102) [1]=>int(103)+2items/

    echo get_item_html( $catalog[$id]);
