thinkPHP分頁功能圖文詳解

這篇文章主要介紹了thinkPHP分頁功能,結合完整執行個體形式分析了thinkPHP基於商品模型實現分頁功能的相關操作技巧,需要的朋友可以參考下

本文執行個體講述了thinkPHP分頁功能。分享給大家供大家參考，具體如下：

interface ServiceInterFace：

<?php/** * InterFaceService * @author yhd */namespace Red;interface ServiceInterFace {  /**   * 執行個體化當前類   */  public static function getInstance();}

StaticService 靜態服務類：

<?php/** * 靜態服務類 * StaticService * @author yhd */namespace Red;class StaticService{  protected static $data;  /**   * 設定待用資料   * @param string $key key   * @param mixed $data data   * @return mixed   */  public static function setData($key,$data){    self::$data[$key] = $data;    return self::$data[$key];  }  /**   * 通過引用使用待用資料   * @param string $key key   * @return mixed   */  public static function & getData($key){    if(!isset(self::$data[$key])){      self::$data[$key] = null;    }    return self::$data[$key];  }  /**   * 緩衝執行個體化過的對象   * @param string $name 類名   * @return 對象   */  public static function getInstance($name){    $key = 'service_@_'.$name;    $model = &self::getData($key);    if($model === null){      $model = new $name();    }    return $model;  }  /**   * html轉義過濾   * @param mixed $input 輸入   * @return mixed   */  public static function htmlFilter($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;  }}
