    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,

    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');
    ?>

    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,

    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');
