Answer 1

I did some small improvement in the script.

  open($zip_name,  ZipArchive::CREATE);
    $files = new RecursiveIteratorIterator(
        new RecursiveDirectoryIterator($directory),
        RecursiveIteratorIterator::LEAVES_ONLY
    );
    foreach ($files as $file) {
        $path = $file->getRealPath();
        //check file permission
        if(fileperms($path)!="16895"){
            $zip->addFromString(basename($path),  file_get_contents($path)) ;
            echo "{$path} is added to zip file.
 " ;
        }
        else{
            echo"{$path} location could not be added to zip
";
        }
    }
    $zip->close();
    ?>
