php广告加载类用法实例

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(); 
  } 
 
   
  public static function setConfig($config=array(), $jsclass=''){ 
    self::$_config = $config; 
    self::$_jsclass = $jsclass; 
  } 
 
 
   
  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']; 
    } 
  } 
 
   
  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; 
  } 
 
   
  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, ''); 
   array_push($html, ''); 
   array_push($html, ''); 
 } 
      } 
 
      array_push($html, ''); 
    } 
    return implode("rn", $html); 
  } 
 
   
  private static function checkBrowser(){ 
    $user_agent = $_SERVER['HTTP_USER_AGENT']; 
    if(strstr($user_agent,'MSIE')!=''){ 
      return false; 
    } 
    return true; 
  } 
 
} // class end 
?>

ADConfig.php文件如下：
