php广告加载类用法实例

php  /  管理员 发布于 7年前   194

本文实例讲述了php广告加载类的用法，非常实用。分享给大家供大家参考。具体方法如下：

该php广告加载类，支持异步与同步加载。需要使用Jquery实现。

ADLoader.class.php类文件如下：

0){       self::$_step = $step;     }      if(isset($async) && is_bool($async)){       self::$_async = $async;     }      // 判断浏览器,如IE强制使用同步加载     if(!self::checkBrowser()){       self::$_async = false;     }      self::getAds($channel);     self::genZoneId();      return self::genHtml();   }    /** 设置config   * @param String $config 广告配置   * @param String $jsclass js class文件路径   */   public static function setConfig($config=array(), $jsclass=''){     self::$_config = $config;     self::$_jsclass = $jsclass;   }     /** 根据channel创建广告集合   * @param String $channel 栏目   */   private static function getAds($channel=''){     $AD_Config = self::$_config;     if($AD_Config!=null){       self::$_ads = isset($AD_Config[$channel])? $AD_Config[$channel] : $AD_Config['default'];     }   }    /** zoneid base64_encode 处理 */   private static function genZoneId(){      // 同步加载广告不需要处理zoneid     if(!self::$_async){       return ;     }      $ads = self::$_ads;     for($i=0,$len=count($ads); $i<$len; $i++){       if(isset($ads[$i]['zoneId'])){         $ads[$i]['zoneId'] = base64_encode('var zoneid='.$ads[$i]['zoneId'].';');       }     }     self::$_ads = $ads;   }    /** 生成广告html */   private static function genHtml(){     $ads = self::$_ads;     $html = array();     if(self::$_jsclass!=null && $ads){       array_push($html, '');        // 同步需要预先加载       if(!self::$_async){         foreach($ads as $ad){           array_push($html, '

ADConfig.php文件如下：

 array(     array(       'type' => 'openx',       'domId' => 'ad_728x90',       'zoneId' => 452     ),     array(       'type' => 'openx',       'domId' => 'ad_300x250',       'zoneId' => 449     ),     array(       'type' => 'openx',       'domId' => 'ad_l2_300x250',       'zoneId' => 394     ),   ),    'case_url' => array(     array(       'type' => 'url',       'domId' => 'ad_728x90',       'url' => 'adurl.php?zoneid=452'     ),     array(       'type' => 'url',       'domId' => 'ad_300x250',       'url' => 'adurl.php?zoneid=449'     ),     array(       'type' => 'url',       'domId' => 'ad_l2_300x250',       'url' => 'adurl.php?zoneid=394'     )   ),    'case_sync_openx' => array(     array(       'type' => 'openx',       'domId' => 'ad_728x90',       'zoneId' => 452     ),     array(       'type' => 'openx',       'domId' => 'ad_300x250',       'zoneId' => 449     ),     array(       'type' => 'openx',       'domId' => 'ad_l2_300x250',       'zoneId' => 394     ),   ),    'default' => array(     array(       'type' => 'openx',       'domId' => 'ad_728x90',       'zoneId' => 452     ),     array(       'type' => 'openx',       'domId' => 'ad_300x250',       'zoneId' => 449     ),     array(       'type' => 'openx',       'domId' => 'ad_l2_300x250',       'zoneId' => 394     ),   ),  );  ?>
