md5_file 远程获取文件md5

php中md5_file 是获取本地的， 现在需要获取远程文件的md5？然后判断是否修改过等。。。 
有案例或者文献请各位指点。。。谢了 

回复讨论(解决方案)

读过来再md5……难道还有其他可能？

读过来再md5……难道还有其他可能？

因为数据在保存在第三方的服务器上，要在对方的服务器上 验证文件是否被修改了

对方输出个md5 给你比较不就好了？要不呢?

服务器可控则在服务器上md5
不可控就取modify时间，时间后于指定时间再拿下来

我试试，刚才想了想，要么 给那个服务器发个请求，服务器就行MD5然后把结果返回去 要么 就是下载后MD5
