theming the li in viewss

I've created a view and themed it, but I would like to give each <li> tag its own id <li id="something">

I know how to give the <ul> tag a custom id, but I don't know how to do it for the <li> tag

This is the original views code:

return theme('item_list', $items);

Changing <ul> to <ol>:

return theme('item_list', $items, NULL, 'ol');

Giving <ul> custom id:

return theme('item_list', $items, NULL, 'ul id="chooserul"');

So my question is: How would I change the <li> tag for the view so that each <li> had a unique id that I could define using an incrementing count? I know just enough php to get myself in trouble, but I'm familiar with other programming code so I understand the concepts well enough.

Here is my full template.php views function

/**
 * views template to output a view.
 * This code was generated by the views theming wizard
 * Date: Mon, 07/07/2008 - 20:33
 * View: bios
 *
 * This function goes in your template.php file
 */
function phptemplate_views_view_list_bios($view, $nodes, $type) {
  $fields = _views_get_fields();

  $taken = array();

  // Set up the fields in nicely named chunks.
  foreach ($view->field as $id => $field) {
    $field_name = $field['field'];
    if (isset($taken[$field_name])) {
      $field_name = $field['queryname'];
    }
    $taken[$field_name] = true;
    $field_names[$id] = $field_name;
  }

  // Set up some variables that won't change.
  $base_vars = array(
    'view' => $view,
    'view_type' => $type,
  );

  foreach ($nodes as $i => $node) {
    $vars = $base_vars;
    $vars['node'] = $node;
    $vars['count'] = $i;
    $vars['stripe'] = $i % 2 ? 'even' : 'odd';
    foreach ($view->field as $id => $field) {
      $name = $field_names[$id];
      $vars[$name] = views_theme_field('views_handle_field', $field['queryname'], $fields, $field, $node, $view);
      if (isset($field['label'])) {
        $vars[$name . '_label'] = $field['label'];
      }
    }
    $items[] = _phptemplate_callback('views-list-bios', $vars);
  }
  if ($items) {
    return theme('item_list', $items);
  }
}
