php 获取优酷视频的真实地址(2014.6月新算法)
上个礼拜发现优酷改版了，各种过滤优酷广告的插件都失效了，于是我百度了一下(谷歌也不能用了)发现优酷改算法了，在ckplayer论坛发现有人在6月25号发了个php 的优酷代理文件，下载下来发现，能用但只能获取mp4格式的视频地址，而且php还加密了，没办法查看源码，后来通过微盾解密发现其中的源码，结合以前自己写的一个优酷视频解析类。。。。感谢 3shi大大 具体分析请见 3shi大大的文章优酷视频真实地址解析（当然现在不能用了，主要看分析）
ps.新算法是从别人那里解密出来的所以有可能存在错误,当然也没有注释,不过我试了几个视频都可以解析。
下面是源码：
