这是一款php分页代码是一款经典的可自动判断url参数再进行分页的实例代码,同时自定了上页,下页,首页,尾页,同时还支持select下拉框跳转代码.
php 经典的分页代码类代码如下:
- class page{
-
- var $page_name="page";
-
- var $next_page='下一页';
-
- var $pre_page='上一页';
-
- var $first_page='首页';
-
- var $last_page='尾页';
-
- var $pre_bar='<<';
-
- var $next_bar='>>';
-
- var $format_left='';
-
- var $format_right='';
-
- var $pagebarnum=5;
-
