php zip creation function is not working on window

I wrote a zip creation function in PHP. It works fine on Ubuntu but when I it throws an error when I use it on a Windows machine. 

<?php

    $Zip = new ZipArchive();
    $filelocation = 'update';
    $Ziplocation = 'ZipVila/ZipEx.zip';
    $Zipfolder = 'ZipVila';

    $Zip->open($Ziplocation, ZipArchive::CREATE | ZipArchive::OVERWRITE);
    $files = scandir($filelocation);

    print_r($files);

    unset($file[0], $file[1]); // Windows throws an "object file is not defined" error in this line   

    foreach ($files as $file) {

        $Zip->addfile($filelocation."/{$file}", $file);
        echo "File Added";

    }

    $Zip->close();

    echo "Zip Closed";

?>

Can anyone help me in this ?

Solution

  • you have an error in

    unset($file[0], $file[1]);

    because $file is not set yet so you can unset it, try this

    unset($files[0], $files[1]);
