Thank you monks!Issue is resolved.
The above code is working when i tried file transfer between two linux systems.
Unfortunately a remote test server was a windows one and the below code fails.
$sftp->put("helloabc.txt", "helloabc.txt");
I have modified the code as below and it started working.
$sftp->put("helloabc.txt", "/D/helloabc.txt"); | [reply]
