How to send file from PHP-script to another PHP-script in code?

I have some web-form which posts some data and user file to first php script.
First script wants to upload received from form file which located at $_FILE variable to second php script (second script wants receive file in $_FILE variable too).

How can I make this?

P.S. Second script located on another web-server.
