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,

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
