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; 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])){ 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 $input 输入 * @return mixed */ public static function htmlFilter($input){ if(is_array($input)) { foreach($input as & $row) { $row = self::htmlFilter($row); } } else { if(!get_magic_quotes_gpc()) { $input = addslashes($input); } $input = htmlspecialchars($input); } return $input; } }
