Using PHP to call a script to manipulate files or ssh?

Question

Hi,

I've been told that this is possible to do with PHP. I have my website and there is a selection box. I would like the options to be populated from the contents of a folder on an sftp server. Then upon click I would like to get the associated files and move them to my local machine. Are there any good tutorials on how to do this? I'm having trouble finding one.

Thanks

Answer 1

This is the way:

use cURL from PHP to query the remove SFTP server, for both listing and file retrieval.

Manual for php is here. You don't need any SSH scripts (which by the way is usually strictly forbidden on most shared hosting environment), if your sFTP server is publicly available. Curl will do everything for you.

You can use exec method http://php.net/manual/en/function.exec.php

<?php
echo exec('ssh -help');
?>

Answer 3

in the selection box you can list the files with:

   if (is_dir($dir)) {
        if ($fh = opendir($dir)) {
            while (($file = readdir($fh)) !== false) {
                if($file != "." && $file != "..") 
                    $files[] = $file;               
            }
            closedir($fh);
        }
    }

to transfer the files from one to another host you can use php exec and scp:

exec('scp host1:/path/to/oldfile host2:/path/to/newfile');
