介绍一款原生的[PHP][]分页类，分页样式有点类似bootstrap。

![Center][]

index.php代码

<?php  
    include_once("config.php");  
    require_once('page.class.php'); //分页类  
    $showrow = 10; //一页显示的行数  
    $curpage = empty($_GET['page']) ? 1 : $_GET['page']; //当前的页,还应该处理非数字的情况  
    $url = "?page={page}"; //分页地址，如果有检索条件 ="?page={page}&q=".$_GET['q']  
    //省略了链接mysql的代码，测试时自行添加  
    $sql = "SELECT * FROM userinfo";  
    $total = mysql_num_rows(mysql_query($sql)); //记录总条数  
    if (!empty($_GET['page']) && $total != 0 && $curpage > ceil($total / $showrow))  
        $curpage = ceil($total_rows / $showrow); //当前页数大于最后页数，取最后一页  
    //获取数据  
    $sql .= " LIMIT " . ($curpage - 1) * $showrow . ",$showrow;";  
    $query = mysql_query($sql);  
    ?>
