PHP抓取、分析国内视频网站的视频信息工具类

只看该作者 · 发表于 2018-2-14 05:59:24

         使用方法：
[U]复制代码[/U] 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。
