How to copy files from server to Dropbox using PHP?

Question

I think I may have found a PHP program to upload files from a specific folder onto my Dropbox account. The full solution can be found here.

The code seems to work because files and folders a like are being uploaded. However, I don't want the files on my server to be compressed beforehand: I want to copy all files with the files and folders within.

How can the code be modified please? All I want is to copy a specific directory called uploads from my server to dropbox. After modifying the code I managed to arrive at this code:

    <?php

    // Set the timezone so filenames are correct
    date_default_timezone_set('Europe/London');

    // Dropbox username/password
    $dropbox_email='[email protected]';
    $dropbox_pass='password';


    // Filenames for backup files
    $backup_files = "files_" . date("Y.m.d-h.i.s_l") . '.zip';


    // File to backup
    $siteroot = "/site/home/public_html/website/parent/child/uploads/";


    // Backup all files in public_html apart from the gz
    system("zip -r $backup_files $siteroot");


    include("DropboxUploader.php");

    $uploader = new DropboxUploader($dropbox_email, $dropbox_pass);
    $uploader->upload($backup_files,'Backup/Files/');

    system("rm $backup_files");

    ?>

Actual Solution Special thanks to Alireza Noori, halfer and everyone else.

<?php

// Set the timezone so filenames are correct
date_default_timezone_set('Europe/London');

// Backup all files in public_html apart from the gz
$siteroot = "/path/to/backup";

$dropbox_email='dropbox@email';  //Dropbox username
$dropbox_pass='pass';   // Dropbox password

include("DropboxUploader.php");

$uploader = new DropboxUploader($dropbox_email, $dropbox_pass);

function FolderToDropbox($dir, $dropbox_link){    
    $dropbox_folder = 'FolderInDropboxRoot/';
    $files = scandir($dir);
    foreach($files as $item){
        if($item != '.' && $item != '..'){
            if(is_dir($dir.'/'.$item)) FolderToDropbox($dir.'/'.$item,$dropbox_link);
            else if(is_file($dir.'/'.$item)) {
                $clean_dir = str_replace("/path/to/backup", "", $dir);
                $dropbox_link->upload($dir.'/'.$item,$dropbox_folder.$clean_dir.'/');  
            } 
        }
    }
}

FolderToDropbox($siteroot,$uploader);

?>

What @halfer is suggesting is this (I just modified your potential solution based on his idea) so he should take credit:

<?php

function uploadx($dirtocopy, $dropboxdir, $uploader){
    if ($handle = opendir($dirtocopy)) {
        while (false !== ($entry = readdir($handle))) {
            if ($entry != "." && $entry != "..") {

                if(is_dir($entry)){
                    uploadx($dirtocopy.$entry.'/', $dropboxdir.$entry.'/', $uploader);
                } else {
                    $uploader->upload($dirtocopy.$entry, $dropboxdir.$entry);
                }

            }
        }
        closedir($handle);
    }
}

// Dropbox username/password
$dropbox_email='[email protected]';
$dropbox_pass='password';

// File to backup
$siteroot = "./";

include("DropboxUploader.php");

$uploader = new DropboxUploader($dropbox_email, $dropbox_pass);

uploadx($siteroot, 'Backup/Files/', $uploader);

?>

BTW, the function above is from here: How to backup files from a specific directory to Dropbox using PHP only?
