UPLOAD FILES USING PHP AND CURL
Recently I was working on one REST API, in which I was sending API request using cURL and to send parameters I was using POST method.
In one of the API request I wanted to send or upload a file through cURL, so I started working and got the solution for the same.
Below is the simple code by which we can upload file using cURL in PHP.
Just copy-paste the below given code in 3 different file and give names as given at top of each code.
uploadform.php: Form with file field

<html>
<head>
<title>File Upload Using PHP and cURL - php-guru.in</title>
<style type="text/css">
body
{
  font-family:Verdana, Geneva, sans-serif;
  font-size:12px;
}
</style>
</head>
<body>
<font style="color: red;"> < ?php echo ucfirst($errmsg);?> </font><br>
<br>
<table border="1" cellspacing="0" cellpadding="3" style="border-collapse:collapse;" bordercolor="#CCCCCC">
  <form action="uploadpost.php" method="post" name="frmUpload" enctype="multipart/form-data">
  <tr>
  <td>Upload</td>
  <td align="center">:</td>
  <td><input name="file" type="file" id="file"/></td>
  </tr>
  <tr>
  <td>&nbsp;</td>
  <td align="center">&nbsp;</td>
  <td><input name="btnUpload" type="submit" value="Upload" /></td>
  </tr>
  </form>
</table>
</body>
</html>
uploadpost.php:
  $errmsg = '';
  if (isset($_POST['btnUpload']))
  {
  $url = "URL_PATH of upload.php"; // e.g. http://localhost/myuploader/upload.php // request URL
  $filename = $_FILES['file']['name'];
  $filedata = $_FILES['file']['tmp_name'];
  $filesize = $_FILES['photo']['size'];
  if ($filedata != '')
  {
  $headers = array("Content-Type:multipart/form-data"); // cURL headers for file uploading
  $postfields = array("filedata" => "@$filedata", "filename" => $filename);
  $ch = curl_init();
  $options = array(
  CURLOPT_URL => $url,
  CURLOPT_HEADER => true,
  CURLOPT_POST => 1,
  CURLOPT_HTTPHEADER => $headers,
  CURLOPT_POSTFIELDS => $postfields,
  CURLOPT_INFILESIZE => $filesize,
  CURLOPT_RETURNTRANSFER => true
  ); // cURL options
  curl_setopt_array($ch, $options);
  curl_exec($ch);
  if(!curl_errno($ch))
  {
  $info = curl_getinfo($ch);
  if ($info['http_code'] == 200)
  $errmsg = "File uploaded successfully";
  }
  else
  {
  $errmsg = curl_error($ch);
  }
  curl_close($ch);
  }
  else
  {
  $errmsg = "Please select the file";
  }
  }


upload.php:File upload code
  $uploadpath = "images/";
  $filedata = $_FILES['filedata']['tmp_name'];
  $filename = $_POST['filename'];
  if ($filedata != '' && $filename != '')
  copy($filedata,$uploadpath.$filename);
