$ Varname = 'my'; // key uploaded to the $ _ FILES array
$ Name = '3.txt '; // file name
$ Type = 'text/plain '; // file type

$ Key = "$ varname \"; filename = \ "$ name \ r \ nContent-Type: $ type \ r \ n ";
$ Fields [$ key] = $ contents;



$ Ch = curl_init ();


Curl_setopt ($ ch, CURLOPT_URL, 'http: // localhost/upload. php ');

Curl_setopt ($ ch, CURLOPT_POST, true );
Curl_setopt ($ ch, CURLOPT_POSTFIELDS, $ fields );
