How do I create a numbered list with PHP? [closed]

Question

I'm having some difficulty functioning this morning! This isn't specifically WP (more PHP), but I think that it would benefit WP devs in the future, so I'm asking here. I'm trying to create a list that does something like this:

$items = get_post_meta($post->ID, "item-specific-meta");
$output = '';
foreach ($items as $item){
  $item_id = $item[#] <--I WANT THIS TO BE A NUMBER
  $output .= '<label for="item-';
  $output .= $item_id;
  $output .= '"><input id="item-';
  $output .= $item_id;
  $output .= '"/>';
  $output .= $item;
  $output .= '</label>';
}

Which would return something like:

<label for="item-1">
  <input id="item-1"/>
  Item 1
</label>

Right now I'm putting the content of the custom meta item in place of the numbered list that I would prefer using. It does the job, but I just don't like all that excess crap that could be done simply.

Like I opened with, my brain isn't working right this morning and I can't even think of the proper search term to Google and answer this myself, so I'm turning to the awesome folks here! Thanks in advance!

This is pure PHP.

$items = get_post_meta($post->ID, "item-specific-meta");
$item_id = 1;
$output = '';
foreach ($items as $item) {
    $output .= '<label for="item-'.$item_id.'"><input id="item-'.$item_id.'"/>'.$item.'</label>';
    ++$item_id;
}
