自己写的一个分页类 ，不是很完整，个别没有做验证，但可以使用，分页效果见文章底部。除了链接数据库的代码没有粘贴上来，其他的都粘贴了。供学习使用～

上面是类文件的所有代码，以下是调用实例：
<?php
//数据库链接,不写了
//每页显示条数
$pageSize = 10;
//页码行显示的条数
$showPage = 5;
//当前页
$page = isset($_GET[‘page‘]) ? $_GET[‘page‘] : 1;
//当前页显示的文章
$sql = "select * from follow_trade_1 order by `follow_trade_id` asc limit ".($page-1)*$pageSize.",{$pageSize}";
$query = mysql_query($sql);
//计算总条数
$sql_count = mysql_query("select count(*) from follow_trade_1");
$query_count = mysql_fetch_row($sql_count);
$count = $query_count[0];
//实例化分页类
require("page.php");
$p = new page($count, $pageSize, $showPage, $page, true);
//table里的文章数据
echo "<table border=‘1‘ style=‘width:400px;‘>";
echo "<tr><td>follow_trade_id</td><td>follow_id</td></tr>";
while($rs = mysql_fetch_assoc($query)) {
echo "<tr><td>{$rs[‘follow_trade_id‘]}</td><td>{$rs[‘follow_id‘]}</td></tr>";
}
echo "</table>";
//读取分页条
$p->GetPagerContent();
样式CSS:
<style>
div.page{text-align: left; margin-top: 10px;}
div.page a{border: 1px solid #aaaadd; text-decoration: none; padding:2px 10px 2px 10px; margin: 2px;}
div.page span.current{border: 1px solid #000099; background-color: #000099; padding: 4px 10px 4px 10px; margin: 2px; color: #fff; font-weight: bold;}
div.page span.disable{border: 1px solid #eee; padding: 2px 5px 2px 5px; margin: 2px; color: #ddd;}
div.page form{display: inline;}
</style>
效果如图所示：
