无法通过php上传文件

Question

I am submitting a file with the following html code to a php file. What I want to do is that get that file in php and then set the file as a parameter's value for cURL as postfields and then execute the url, How can I do that?

Here is the html :

   <form name="frm" id="frm" method="post" action="fileSubmit.php" enctype="multipart/form-data">
      <input type="file" name="file" id="file"/>
      <input type="submit" name="submit" value="submit" />
   </form>

Here is the php

<?php 
if(isset($_REQUEST['submit'])) { 
  $curl = curl_init("myDomain/submitFile";); 
  $file = "file=".file_get_contents($_FILES["file"]["name"]);
  curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1); 
  curl_setopt($curl, CURLOPT_HEADER, 0); 
  curl_setopt($curl, CURLOPT_TIMEOUT, 60); 
  curl_setopt($curl, CURLOPT_POST, 0);
  curl_setopt($curl, CURLOPT_POSTFIELDS, $file); 
  $resp = curl_exec($curl); 
  curl_close($curl); 
} 
?>

Thanks in advance!

try

$_FILES["file"]["tmp_name"]

instead, until you move the uploaded file it is stored in a temporary location
