thinkPHP分页功能实例详解

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
/**
 * 静态服务类
 * StaticService
 * @author yhd
 */
namespace Red;

  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])){
      self::$data[$key] = null;
    }
    return self::$data[$key];
  }
  /**
   * 缓存实例化过的对象
   * @param string $name 类名
   * @return 对象
   */
  public static function getInstance($name){
    $key = "service_@_".$name;
    $model = &self::getData($key);
    if($model === null){
      $model = new $name();
    }
    return $model;
  }
  /**
   * html转义过滤
   * @param mixed $input 输入
   * @return mixed
   */

}
