想了解thinkPHP分页功能实例详解的相关内容吗,yhdsir在本文为您仔细讲解thinkPHP分页的相关知识和一些Code实例,欢迎阅读和指正,我们先划重点:thinkPHP,分页,下面大家一起来学习吧。

本文实例讲述了thinkPHP分页功能。分享给大家供大家参考,具体如下:

interface ServiceInterFace:

<?php
/**
 * InterFaceService
 * @author yhd
 */
namespace Red;
interface ServiceInterFace {
  /**
   * 实例化当前类
   */
  public static function getInstance();
}

StaticService 静态服务类:

<?php
/**

 * StaticService
 * @author yhd
 */
namespace Red;
class StaticService{
  protected static $data;
  /**
   * 设置静态数据
   * @param string $key key
   * @param mixed $data data
   * @return mixed
   */
  public static function setData($key,$data){
    self::$data[$key] = $data;
    return self::$data[$key];
  }

   * 通过引用使用静态数据
   * @param string $key key
   * @return mixed
   */
  public static function & getData($key){
    if(!isset(self::$data[$key])){

    }
    return self::$data[$key];
  }
  /**
   * 缓存实例化过的对象
