我正在尝试使用 sftp 连接从服务器下载文件并将其保存在我的服务器上

Question

I'm trying to download a file from the server using sftp connection and save it on my server but the file is empty.

$connection = ssh2_connect('{my server ip}', 22);
ssh2_auth_password($connection, '{user}', '{password}');
$sftp = ssh2_sftp($connection);
$file = "test.txt";
$target_path = "ssh2.sftp://$sftp/public_html/$file";
$stream = fopen($target_path, 'r');
fopen($file, "w");
fclose($stream);

Answer 1

You never copy the data between the opened files/handles. Easy way to do that is using stream_copy_to_stream :

$local_stream = fopen($file, "w");
stream_copy_to_stream($stream, $local_stream);
fclose($local_stream);

As @KenLee commented, if your server supports SCP too (most do), you can replace 6 lines of the code with simple ssh2_scp_recv :

ssh2_scp_recv($connection, "/public_html/$file", $file);
