本文实例讲述了php+ajax实现无刷新分页实现方法。分享给大家供大家参考。具体如下：

    limit 偏移量，长度;
    limit 0,7;   第一页
    limit 7,7;   第二页
    limit 14,7; 第三页
每页信息条数：7
信息总条数：select count(*) from table
信息总页数：ceil向上取整(总条数/每页条数)
1、分页类具体使用

<?php

class Pagination {

  private $total; //数据表中总记录数
  private $listRows; //每页显示行数
  private $limit; //mysql 数据库的limit
  private $uri; //分页信息前面的uri地址
  private $pageNum; //页数
  private $config = array('header' => "个记录", "prev" => "【】", "first" => "【首 页】", "last" => "【尾 页】");
  private $listNum = 8;

  /*
   * $total 当前信息总条数
   * $listRows 每页显示的条数
   * $pa 下面的page
    http://网址/index.php?page=5
   */

  public function __construct($total, $listRows = 10, $pa = "") {
    $this->total = $total;
    $this->listRows = $listRows;
    $this->uri = $this->getUri($pa);
    $this->page = !empty(<p>本文实例讲述了php+ajax实现无刷新分页实现方法。分享给大家供大家参考。具体如下：</p>
