How to transfer files via SFTP in PHP

It's been a long time since my last post and good I'm back again. Anyway, below is my simple script to transfer files via SFTP in PHP. Hope this helps.

<?php

// set your sftp credential (host, port, username, password)
// local file (source file)
// remote file (destination file)


$host = '<host server to connect>';
$port = '<port to connect>';
$user = '<username to sftp>';
$pass = '<password to sftp>';
$lfile = '/path/to/local/file';
$rfile = '/path/to/remote/file';

// use ssh2 php module to connect

// if ssh2 is not installed/enable, please install/enable)
$connection = ssh2_connect($host, $port);
ssh2_auth_password($connection, $user, $pass);

// use sftp to connect
$sftp = ssh2_sftp($connection);

// open stream connection to remote server
$stream = @fopen('ssh2.sftp://'.$sftp.$rfile, 'w');

try {
    if (!$stream) throw new Exception("Could not open remote file: $rfile");

    // get data of the local file
    $data = @file_get_contents($lfile);
    if ($data === false) throw new Exception("Could not open local file: $lfile.");

    // write the data to stream remote file
    if (@fwrite($stream, $data) === false) throw new Exception("Could not send data from file: $lfile.");
    echo 'done!';

} catch (Exception $e) {
    // echo error message
    echo $e->getMessage();
}

// closing the stream
fclose($stream);

?>


Hope this helps and please leave a post if you like it. Thanks!!

  1. I prefer phpseclib, a pure PHP SFTP implementation:

    http://phpseclib.sourceforge.net/

    It's more portable, more reliable and surprisingly faster too in my experience.

  2. I can give that a try but the script above can work without including any library like NET/SFTP.php, you just have to enable/install SSH2 on PHP. Anyway, thank you for the source. Appreciate it! I'll try this.

    1. Hmm.. the error says they can't open the remote file, so the problem here is on the remote server.. Please try to ssh to the server first then try this command upon doing ssh.. "cd /home/budgetdb/tm1/test" and see if you can go to that directory.. if not, then you don't have that directory on the server or probably the user you are using to connect doesn't have access to that directory. Hope that helps.

  4. www.monstaftp.com offers SFTP/SCP as well as normal FTP through a web-based client that's free to download. (disclaimer: I'm involved with this project)
