该php分页类的具体代码以及使用方法如下:

/**
*PHP分页类
 *
*show(2) 1 ... 62 63 64 65 66 67 68 ... 150
*分页样式
*#page{font:12px/16px arial}
*#page span{float:left;margin:0px 3px;}
*#page a{float:left;margin:0 3px;border:1px solid #ddd;padding:3px
*7px;text-decoration:none;color:#666}
*#page a.now_page,#page a:hover{color:#fff;background:#05c}

类使用示例:

###处理html静态化页面分页的情况###
# method 处理环境 设置为 html
# parameter 为静态页面参数  www.maopiaopiao.com/20-0-0-0-40-?.html 注意问号
# ?问号的位置会自动替换为去向页码
# now_page 当前页面(静态页面获取不到当前页面所以只有你传入)
$params=array(
            'total_rows'=>100,#(必须)
            'method'    =>'html',#(必须)
            'parameter' =>'www.maopiaopiao.com/20-0-0-0-40-?.html', #(必须)
            'now_page'  =>$_GET['p'], #(必须)
            'list_rows' =>10,#(可选) 默认为15
);
$page=new Pager($params);
   echo $page->show(1);
   #<a href="www.maopiaopiao.com/20-0-0-0-40-2.html">2</a>

###处理ajax分页的情况###
# method 处理环境 设置为 ajax
# ajax_func_name ajax分页跳转页面的javascript方法
# parameter    ajax_func_name后面的附带参数 默认为空
# now_page 不到当前页面所以只有你传入
$params=array(
            'total_rows'=>100,
            'method'    =>'ajax',
            'ajax_func_name' =>'goToPage',
            'now_page'  =>1,
            #'parameter' =>"'jiong','username'",
);
$page=new Pager($params);
echo $page->show(1);
#<a href="javascript:void(0)" onclick="goToPage('7')">7</a>
#添加了parameter<a href="javascript:void(0)" onclick="goToPage('6','jiong','username')">6</a>
