PHP抓取、分析国内视频网站的视频信息工具类的简单示例

人气：267 时间：2021-08-24

这篇文章主要为大家详细介绍了PHP抓取、分析国内视频网站的视频信息工具类的简单示例，具有一定的参考价值，可以用来参考一下。

感兴趣的小伙伴，下面一起跟随四海网的小玲来看看吧！

使用方法：

代码如下:


require_once "VideoUrlParser.class.php";
$url = "http://v.youku.com/v_show/id_XMjkwMzc0Njg4.html";
$info = VedioUrlParser::parse($url);
echo $info;

说明：调用该工具php文件VideoUrlParser.class.php，$url变量后面的字符串为视频页的地址，然后使用echo输出变量$info。
附：info含有的几个值，分别是img（用于视频缩略图），title（视频标题），url（地址），swf（视频swf播放地址）。我只用到了img和swf地址。具体的可以根据自己的需要进行调整。

 


VideoUrlParser类源码：
