向函数添加筛选器。主题的php是一种可能性：

add_filter(\'wp_list_categories\', \'cat_count_span\');
function cat_count_span($links) {
  $links = str_replace(\'</a> (\', \'</a> <span>(\', $links);
  $links = str_replace(\')\', \')</span>\', $links);
  return $links;
}

或将代码更改为：

$args = array(                 
  \'hide_empty\' => FALSE,                 
  \'title_li\'=> __( \'\' ),                 
  \'show_count\'=> 1,             
  \'echo\' => 0
);             
  $links = wp_list_categories($args);
  $links = str_replace(\'</a> (\', \'</a> <span>(\', $links);
  $links = str_replace(\')\', \')</span>\', $links);
echo $links;
