Re: Hoping for a working example of SFTP in PHP

[Scott Lucas <scott.lucas@xxxxxxxxxxxxxxxxxxxxxxx>]

This is code that we use for the ssh2 library (with password auth). You will need to replace the auth function for key usage: https://www.php.net/manual/en/function.ssh2-auth-pubkey-file.php

        $error = false;
        $connection = ssh2_connect('host.name', 22);
        if ($connection) {
          if (ssh2_auth_password($connection, 'username', 'password')) {
            $sftp = ssh2_sftp($connection);
            if ($sftp) {
              try {
                $sftpStream = fopen('ssh2.sftp://' . intval($sftp) . MODULE_SFTP_FOLDER . $filename_remote, 'w');
                if (!$sftpStream) {
                  throw new Exception("Could not open remote file: $filename_remote");
                }
                $data_to_send = file_get_contents('manifests/' . $filename);
                if ($data_to_send === false) {
                  throw new Exception("Could not open local file: manifests/$filename.");
                }
                if (fwrite($sftpStream, $data_to_send) === false) {
                  throw new Exception("Could not send data from file: manifests/$filename.");
                }
                fclose($sftpStream);
                $success = true;
              } catch (Exception $e) {
                $success = false;
                $error = $e->getMessage();
                error_log('Exception: ' . $e->getMessage());
                if ($sftpStream) fclose($sftpStream);
              }
              if (!$success) {
                $error = true;
              }
              ssh2_exec($connection, 'exit');
              unset($connection);

            } else {
              $error = true;
            }
          } else {
            $error = true;
          }
        } else {
          $error = true;
        }

Hope that helps,

Kind regards,

Scott

rsync: an alternate to sftp:

# Upload to example.com/dir/
rsync -avzhe ssh \
   /local_dir/dir/TheFile.ext \
      remote_user@xxxxxxxxxxx:/public_html/dir/
