Uploading a file using WebDav protocol from Unix - php

Question

I need to transfer a file from my Unix machine to a Windows machine. Problem is i can transfer a file already created on my machine via ftp from unix to any machine. also i can open webdav connection create new file and save it there.
What i am unable to do is to write my code to upload my file fro my local location using webdav.
i tried using pear client but due to lack of documentation, i am still not able to achieve the task .
Here is my attempt:
include("/usr/share/pear/HTTP/WebDAV/Client.php");
global $filename, $logger;
try {
/* $client = new HTTP_WebDAV_Client();
$user="username";
$pass = "pwd";
$dir = "webdavs://".$user.":".$pass."#hostname/";
var_dump($client->stream_open($dir."test4.txt","w",null,$path));
$client->stream_write("HELLO WORLD! , I am great ");
$client->stream_close();
$client->dir_opendir($dir,array());
var_dump($client->dirfiles);
$req =new HTTP_Request($dir);
$req->setBasicAuth($user, $pass);
$req->setMethod(HTTP_REQUEST_METHOD_POST);
$result = $req->addFile('file_upload_field', $filename);
if (PEAR::isError($result)) {
echo $result->getMessage();
} else {
$response = $req->sendRequest();
if (PEAR::isError($response)) {
echo $response->getMessage();
} else {
echo $req->getResponseBody();
}
}*/
$ftp_server = "hostname-ftp";
//$ftp_server = "hostname-webdav";
$connection = ftp_connect($ftp_server);
ftp_login($connection, 'user', 'pwd);
ftp_put($connection, $filename, $filename, FTP_BINARY);
unlink($filename);
} catch(Exception $e){
$message = "There was a problem while uploading" . $filename;
$logger->error($message);
}

It was a togh call, but i figured it out. I am adding my code snippet so it may be helpful for someone. Instead of uploading the file, i converted that file into data stream and then copied that data stream to my call that writes stream on webdav server.
try {
$filecsv = file_get_contents($filename);
$client = new HTTP_WebDAV_Client_Stream();
$user="user";
$pass = "pass";
$dir = "webdavs://".$user.":".$pass."#hostname/";
$client->stream_open($dir."db_user_exports.csv","w",null,$path);
$client->stream_write($filecsv);
$client->stream_close();
unlink($filename);
} catch(Exception $e){
$message = "There was a problem while uploading" . $filename;
$logger->error($message);
}
