为什么我的zip文件无效或损坏（Windows无法打开文件夹）？

I´m trying to make a zip with some file in my DB, and I do just some other things before I packed on a zip, I actually read files to another server and write them in the same folder to packing, but for some reason my zip file downloaded as invalid.

I actually see the answers related to this issue but they did not help me. Here´s my script:

<?php 
include_once('..databaseconnection');
include_once('..databaseconnection');

function noticiaZip($idNoticia)
{
    //Utilizo el idTarea para traer las tareas del post correspondiente

    sql="Query->";

    $result = mysql_query($sql);
    $arrgArch = array();
    while ($row = mysql_fetch_array($result)) {
        $arrgArch[] = array('Archivo' =>$row['link'], 
                            'Nombre'=>utf8_encode($row['Nombre']),
                            'Titulo'=>utf8_encode($row['Titulo']) 
                            );
    }
    $zip = new ZipArchive();

    $filename = 'example.zip';

    if($zip->open($filename, ZipArchive::CREATE)===true) {
        foreach ($arrgArch as  $value) {

            //Divido el url para poder rescatar el nombre del archivo
            $nameFile = explode('/', $value['Archivo']);
            $count = count($nameFile);
            $name = $count - 1;

            //Url con el code para los espacios y que me acepte realizar el stream
            $url = str_replace($nameFile[$name], rawurlencode($nameFile[$name]), $value['Archivo']);
            $source =$url;

            $destination = $nameFile[$name];

            $data = file_get_contents($source);

            $handle = fopen($destination, "w+");
            $noticias = fopen("noticia.doc", "w+");

            fwrite($handle, $data);
            fclose($handle);

            $verNoticia=traeNoticiaN($idNoticia);

            foreach($verNoticia as $k => $v){
                fwrite($noticias, "Título:
".$v['Titulo']."


");
                fwrite($noticias, "Título:
".$v['value']."


");
                fwrite($noticias, "Título:
".$v['value']."


");
                fwrite($noticias, "Título:


".$v['value']."


");
                fwrite($noticias, "Título:


".$v['value']."


");
                fwrite($noticias, "Título:

".$v['value']."


");
                fwrite($noticias, "Título:

".$v['value']."


");
                fclose($noticias);
            }
            if($value!='noticiaZip.php') {
                $zip->addFile("temp/".$destination, $destination);
                $zip->addFile("temp/noticia.doc", "noticia.doc");
            }
        }
        $zip->close();
        foreach ($arrgArch as $value) {
            $nameFile = explode('/', $value['Archivo']);
            $count = count($nameFile);
            $name = $count - 1;
            $destination = $nameFile[$name];
            unlink($destination);
            unlink("noticia.doc");
        }          
    } // Set headers
    header("Content-type: application/zip");
    header("Content-disposition: attachment; filename=".basename($filename));
    header("Expires: 0");
    header("Cache-Control: must-revalidate, post-check=0,pre-check=0");
    header("Pragma: public"); // Sin esto el IE no funciona
    header("Content-Transfer-Encoding: binary");
    header("Content-Length:".filesize($filename));

    ob_clean();
    readfile($filename);
    unlink($filename); 
    exit();
}
$noti = noticiaZip($_GET['idNoticia']);
