thinkPHP分页功能实例详解
作者：yhdsir
这篇文章主要介绍了thinkPHP分页功能,结合完整实例形式分析了thinkPHP基于商品模型实现分页功能的相关操作技巧,需要的朋友可以参考下
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
*/

* 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
*/
