PHP implements file transfer issues between different servers
I want to implement the design of a button on the local host, click the button to upload the selected data to server A to save, and then upload the file saved by server A to
Site B, then from site B back to a file to download to server A and local, I have implemented the local to server a communication function, now do not know what function or method in PHP can enable the program to automatically achieve the second layer of communication problems, you heroes!

------Solution--------------------
Use the header to send data to site B, in detail depending on the situation, for example, how the site B receives, how large the file, type has no restrictions, and so on.
------Solution--------------------
I don't know what you're trying to do,
Do a file server is not fully resolved.
If one cannot solve, design multiple, and then synchronize data between file servers.
