ssh2_scp_send

In addition to my previous post, I figured out that sftp->fopen->file_get_contents->fwrite has much better performance than ssh2_scp_send.I've used the following code to test:<?php$srcFile = '/var/tmp/dir1/file_to_send.txt';$dstFile = '/var/tmp/dir2/file_received.txt';// Create connection the the remote host$conn = ssh2_connect('my.server.com', 22);// Create SFTP session$sftp = ssh2_sftp($conn);$sftpStream = @fopen('ssh2.sftp://'.$sftp.$dstFile, 'w');try {    if (!$sftpStream) {        throw new Exception("Could not open remote file: $dstFile");    }        $data_to_send = @file_get_contents($srcFile);        if ($data_to_send === false) {        throw new Exception("Could not open local file: $srcFile.");    }        if (@fwrite($sftpStream, $data_to_send) === false) {        throw new Exception("Could not send data from file: $srcFile.");    }        fclose($sftpStream);                    } catch (Exception $e) {    error_log('Exception: ' . $e->getMessage());    fclose($sftpStream);}?>For the test I've sent three files with total size of 6kB, and the times to send including connect to the server were:SFTP -> 15 sec.ssh2_scp_send -> 22 sec.Cheers,Pimmy

After some testing I figured out that ssh2_scp_send does not work exactly as the standard scp command:- Works: ssh2_scp_send($conn, '/var/tmp/file_01.txt', /var/tmp/file_02.txt');- Wrong: ssh2_scp_send($conn, '/var/tmp/file_01.txt', /var/tmp'); (Creates file with name 'tmp')- Fails: ssh2_scp_send($conn, '/var/tmp/file_01.txt', /var/tmp/');- Fails: ssh2_scp_send($conn, '/dirname', /var/tmp/'); (No recursion)- Fails: ssh2_scp_send($conn, '/dirname/*', /var/tmp/'); (Cannot copy more than one file.)Cheers,Pimmy

On Windows, I had trouble using ssh2_scp_send: files copied to a remote server where incomplete (truncated) and/or locked (error message : "access denied"). The back-end is also on Windows, using CopSSH (cygwin-based SSH server).

The SSH session was kept open - and the file were never flushed to disk.

There's a workaround though - make an explicit call to "exit" to close the session (flushing file content to disk):

<?php
  $objConnection = ssh2_connect($strHost, $strPort, $methods, $callbacks);
  ssh2_auth_password($objConnection, $strUser, $strPassword);
  ssh2_scp_send($objConnection , $strSource, $strDest);

  // Add this to flush buffers/close session
  ssh2_exec($objConnection, 'exit');
?>

In case the command:$sftpStream = @fopen('ssh2.sftp://'.$sftp.$dstFile, 'w');causes you a segmentation fault, try using:$sftpStream = @fopen('ssh2.sftp://'.intval($sftp).$dstFile, 'w');Credit: http://stackoverflow.com/questions/7414175/php-sftp-seg-fault
