Answer 1

// Function to recursively add a directory,
// sub-directories and files to a zip archive
function addFolderToZip($dir, $zipArchive, $zipdir = ''){
if (is_dir($dir)) {
    if ($dh = opendir($dir)) {

        //Add the directory
        $zipArchive->addEmptyDir($dir);

        // Loop through all the files
        while (($file = readdir($dh)) !== false) {

            //If it's a folder, run the function again!
            if(!is_file($dir . $file)){
                // Skip parent and root directories
                if( ($file !== ".") && ($file !== "..")){
                    addFolderToZip($dir . $file . "/", $zipArchive, $zipdir . $file . "/");
                }

            }else{
                // Add the files
                $zipArchive->addFile($dir . $file, $zipdir . $file);

            }
        }
    }
}
}
