How can I remove the `<` from the breadcrumb I tried `implode('<', $value['data'])` but no luck

```
   function bootstrap_fit_breadcrumb($variables) {
            $breadcrumb = $variables['breadcrumb'];

            if (!empty($breadcrumb)) {
              //$breadcrumb[] = drupal_get_title();
              $breadcrumbs = '<ul class="breadcrumbs_list">';

              $count = count($breadcrumb) - 1;

              foreach ($breadcrumb as $key => $value) {
                  if ($key==0) {
                    $breadcrumbs .= '<li>' . $value . '</li>';
                  } else {
                   $breadcrumbs .= '<li><span></span>' . $value['data'] . '</li>';

                  }
              }
              $breadcrumbs .= '</ul>';
              return $breadcrumbs;
      }
   }
