php广告加载类用法实例

2024-04-08 02:22:03 24

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：

<?php
/**广告加载管理类
*Date:2013-08-04
*Author:fdipzone
*Ver:1.0
*
*Func:
*publicload加载广告集合
*publicsetConfig广告配置

*privategenZoneIdzoneidbase64_encode处理
*privategenHtml生成广告html
*privatecheckBrowser检查是否需要同步加载的浏览器
*/

classADLoader{//classstart

privatestatic$_ads=array();//广告集合
privatestatic$_step=300;//广告加载间隔
privatestatic$_async=true;//是否异步加载
privatestatic$_config=array();//广告设置文件

array_push($html,'</script>');
}
returnimplode("\r\n",$html);
}

/**判断是否需要强制同步加载的浏览器*/
privatestaticfunctioncheckBrowser(){
