PHP抓取、分析国内视频网站的视频信息工具类
VideoUrlParser是一款基于PHP根据视频URL抓取视频信息的工具，支持优酷、土豆、酷六、56、乐视、搜狐、腾讯、新浪。
使用方法：
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。
