在PHP中压缩文件夹的内容

Before marking this post as a duplicate, please note that I have already searched for answer on SO and the once I've found so far (listed below) haven't been exactly what I've been looking for.

Those are just some of the ones I've looked at.

My problem is this: I can't use addFromString, I have to use addFile, it's a requirement of the task.

I've already tried a couple of ways, here's my current iteration:

public function getZippedFiles($path)
{
    $real_path = WEBROOT_PATH.$path;

    $files = new RecursiveIteratorIterator (new RecursiveDirectoryIterator($real_path), RecursiveIteratorIterator::LEAVES_ONLY);

    //# create a temp file & open it
    $tmp_file = tempnam($real_path,'');
    $zip_file = preg_replace('"\.tmp$"', '.zip', $tmp_file);

    $zip = new ZipArchive();
    $zip->open($zip_file, ZipArchive::CREATE);

    foreach ($files as $name=>$file)
    {
        error_log(print_r($name, true));
        error_log(print_r($file, true));
        if ( ($file == ".") || ($file == "..") )
        {
            continue;
        }

        $file_path = $file->getRealPath();
        $zip->addFile($file_path);
    }

    $zip->close();
}

When I try to open the resulting file, I get told that "Windows cannot open the folder. The Compressed(zipped) Folder '' is invalid."

I've managed to succesfully complete the task using addFromString, like so:

$file_path = WEBROOT_PATH.$path;
    $files = array();
    if (is_dir($file_path) == true)
    {
        if ($handle = opendir($file_path))
        {
            while (($file = readdir($handle)) !== false)
            {
                if (is_dir($file_path.$file) == false)
                {
                    $files[] = $file_path."\\".$file;
                }
            }

            //# create new zip opbject
            $zip = new ZipArchive();

            //# create a temp file & open it
            $tmp_file = tempnam($file_path,'');
            $zip_file = preg_replace('"\.tmp$"', '.zip', $tmp_file);

            $zip->open($zip_file, ZipArchive::CREATE);

            //# loop through each file
            foreach($files as $file){

                //# download file
                $download_file = file_get_contents($file);

                //#add it to the zip
                $zip->addFromString(basename($file),$download_file);

            }

            //# close zip
            $zip->close();
        }
    }
}

The above is mostly just copied straight from some example code I saw somewhere. If anyone can point me in a good direction I'd be very grateful!

***** UPDATE ***** I added an if around the close like this:

if (!$zip->close()) {
    echo "failed writing zip to archive";
}

The message gets echoed out, so obviously the problem is there. I've also checked to make sure the $zip->open() works, and I've confirmed that it is opening it without a problem.
