rest - PHP cURL HTTP PUT -

i trying create http put request curl , can't make work. i've read many tutorials none of them worked. here's current code:

$filedata = array('metadata' => $rdfxml); $ch = curl_init($url); $header = "content-type: multipart/form-data; boundary='123456f'"; curl_setopt($ch, curlopt_verbose, 1); curl_setopt($ch, curlopt_url, $url); curl_setopt($ch, curlopt_customrequest, "put"); curl_setopt($ch, curlopt_returntransfer, 1); curl_setopt($ch, curlopt_httpheader, array($header)); curl_setopt($ch, curlopt_postfields, http_build_query($filedata)); $returned = curl_exec($ch);  if (curl_error($ch)) {     print curl_error($ch); } else {     print 'ret: ' .$returned; }
