php广告加载类用法实例,php加载用法实例
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(); } /** 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); $i'); // 同步需要预先加载 if(!self::$_async){ foreach($ads as $ad){ array_push($html, ''); } } array_push($html, ''); } return implode("\r\n", $html); } /** 判断是否需要强制同步加载的浏览器 */ 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:
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 ), ), ); ?>
ADLoader.js文件如下:
