modificar archivo php de exportar a zip a dejar archivos en carpeta

Hola estimada comunidad :
Necesito modificar un gestor de construccion de paginas web, modificando la funcion de exportar para que en vez de descargar un archivo en zip, deje los archivos en el mismo servidor, en la carpeta public_html.

el archivo php que descarga la pagina web en zip tiene este codigo

Código PHP :

<?php

/* CONFIG */

$pathToAssets = array("elements/bundles");

$filename = "tmp/website.zip"; //use the /tmp folder to circumvent any permission issues on the root folder

/* END CONFIG */


$zip = new ZipArchive();

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


//add folder structure

foreach( $pathToAssets as $thePath ) {

// Create recursive directory iterator
$files = new RecursiveIteratorIterator(
new RecursiveDirectoryIterator( $thePath ),
RecursiveIteratorIterator::LEAVES_ONLY
);

foreach ($files as $name => $file) {

if( $file->getFilename() != '.' && $file->getFilename() != '..' ) {

// Get real path for current file
$filePath = $file->getRealPath();

$temp = explode("/", $name);

array_shift( $temp );

$newName = implode("/", $temp);

// Add current file to archive
$zip->addFile($filePath, $newName);

}

}

}



foreach( $_POST['pages'] as $page=>$content ) {

$pageContent = stripslashes($content);
$pageContent = str_replace("../bundles/", "bundles/", $pageContent);

$zip->addFromString($page.".html", $_POST['doctype']."\n".stripslashes($pageContent));

//echo $content;

}

//$zip->addFromString("testfilephp.txt" . time(), "#1 This is a test string added as testfilephp.txt.\n");
//$zip->addFromString("testfilephp2.txt" . time(), "#2 This is a test string added as testfilephp2.txt.\n");

$zip->close();


$yourfile = $filename;

$file_name = basename($yourfile);

header("Content-Type: application/zip");
header("Content-Transfer-Encoding: Binary");
header("Content-Disposition: attachment; filename=$file_name");
header("Content-Length: " . filesize($yourfile));

readfile($yourfile);

unlink('website.zip');

exit;
?>
