   if(file_exists($destination) && !$overwrite) { return false; }

   $validFiles = array();
   if(is_array($files)) {
      foreach($files as $file) {
         if(file_exists($file)) {
            $validFiles[] = $file;

   if(count($validFiles)) {
      $zip = new ZipArchive();
      if($zip->open($destination,$overwrite ? ZIPARCHIVE::OVERWRITE : ZIPARCHIVE::CREATE) == true) {
         foreach($validFiles as $file) {
         return file_exists($destination);
          return false;
      return false;

$fileName = '';
$files = array('uploads/profile1.png', 'uploads/profile2.png');
