You may have an easier time using phpseclib, a pure PHP SFTP client . Here is an example:

<?php include('Net/SFTP.php'); $sftp = new Net_SFTP('www.domain.tld'); if (!$sftp->login('username', 'password')) { exit('Login Failed'); } echo $sftp->pwd() . "\r\n"; $sftp->put('filename.ext', 'hello, world!'); print_r($sftp->nlist()); ?>

The problem with libssh2, like all recommendations, is that it is not very widespread, this API is not quite the most reliable, it is unreliable, poorly supported, etc.

Is Apache Server Installed? for example: xampp?

If you do this, you use the FTP function:

 <?php $connection = ssh2_connect('ftp.server.com', 22); //port 22 for Shell connections ssh2_auth_password($connection, 'username', 'password'); $shell_ftp = ssh2_sftp($connection); $connectionStream = fopen('ssh2.sftp://'.$shell_ftp.'/path/to/fileorfolder', 'r'); if(!connectionStream) { echo "Could not connect to the server, please try agian"; } else { echo "Successfully logged in."; } ?>

To establish a basic connection to the Shell server, you must specify the absolute path to the file or folders.
