//用法1：
echo Page::instance(32,10,5,5,'show?p=','&lang=zh')->show();
//用法2：
echo Page::instance()->show(32,10,5,5,'show?p=','&lang=zh');
//用法3：
$page = Page::instance();
$page->set_config('theme', ' %first% %up% %prev% %page% %next% %down% %last% ');
echo $page->show(32,10,5,5,'show?p=','&lang=zh');
//用法4：
$page = Page::instance(32,10,5,5,'show?p=','&lang=zh');
echo $page->get('page_theme');
echo $page->get('next');//获取下一页，这里显示有设置的主题
//用法5：
$page = Page::instance();
$page->set(32,10,5,5,'show?p=','&lang=zh');
echo $page->get('page_theme');
echo $page->get('next');//获取下一页，这里显示有设置的主题
//注：该类不能对已设数据进行覆盖，比如32,10这些在同一次的执行中不能被其他数据覆盖。如果要进行覆盖，可将已设数据更改为NULL
