Using PHP to transfer a txt file from one server to another - php

Question

Thank you.
Here is the cURL ftp code I have tried to use most recently, together with the response I am getting.
$str contains ascii text (a php script).
I have no problems at all accessing
ftp://hostingdomain/auth/
and the files within it, on a read or write basis, with an FTP client
(in the case OSX Fetch) in either passive or active mode.
In essence, I am trying to create (write) test.php within
ftp://hostingdomain/auth/
, and overwrite it if it is already there. The tmp file is being correctly created,
and deleted once the script exits.
$ch = curl_init();
$tmp = tmpfile();
fwrite($tmp, $str);
fseek($tmp, 0);
curl_setopt($ch, CURLOPT_URL, 'ftp://hostingdomain/auth/test.php');
curl_setopt($ch, CURLOPT_USERPWD, "myftpusername:myftppassword");
curl_setopt($ch, CURLOPT_VERBOSE, 1);
curl_setopt($ch, CURLOPT_UPLOAD, 1);
curl_setopt($ch, CURLOPT_INFILE, $tmp);
curl_setopt($ch, CURLOPT_INFILESIZE, strlen($str));
curl_exec ($ch);
$error_no = curl_errno($ch);
$error = curl_error($ch);
$info = curl_getinfo($ch);
curl_close ($ch);
fclose($tmp);
if ($error_no == 0) {
$message = 'File uploaded successfully.';
} else {
$message = '<BR>File upload error: '.$error_no.' '.$error.'<BR>';
print_r ($info);
}
echo $message;
--------Response - Script is being run on "sending" server.

File upload error: 7

Essentially I am getting a timeout and then the above $info and $message
comes back. Doing exactly the same transfer into
ftp://hostingdomain/auth/test.php with my FTP client works just fine.
