     {echo ('Unable to create SFTP connection.');}


  $localDir  = 'file:///home/hhh/Downloads/dbs';
  $remoteDir = '/home/backup/Dropbox/dbs';
  // download all the files
  $dir = ('ssh2.sftp://' . $sftp . $remoteDir);

I have been trying to download the latest FILES from a directory using sftp. I have only managed to download ONE file instead to 10. I also was able to tweak it to download all the files but that is not i what I was after.

I would like to make it work so that I can be able to download a certain X number of files.

#!/usr/bin/php

<?php
$username = "user";
$password = "password";
$url      = "host ip";
// Make our connection
$connection = ssh2_connect($url);

// Authenticate
if (!ssh2_auth_password($connection, $username, $password))
     {echo('Unable to connect.');}

// Create our SFTP resource
if (!$sftp = ssh2_sftp($connection))
     {echo ('Unable to create SFTP connection.');}

//$dir
$localDir  = "/path/to/localdir/".date('Y-m-d');
exec("mkdir -p '$localDir'");
echo $localDir;


$remoteDir = "/path/to/remotedir";
 // download all the files
$files = scandir ('ssh2.sftp://' . $sftp . $remoteDir);
if (!empty($files)) {
  foreach ($files as $file) {
    if ($file != '.' && $file != '..') {
        if (substr($file, 0, 11)== date('d-M-Y')) {

            //date('d-M-Y', strtotime('yesterday') #for retriving the previous day
            # code...
             // echo $file;
              ssh2_scp_recv($connection, "$remoteDir/$file", "$localDir/$file");

        }

    }
  }
}
 ?>

This downloads the latest files from a remote directory and creates a new local directory by date where it downloads the new remote files
