php - 无法在 ubuntu 服务器上打开 zip 文件错误

Question

我必须一次下载多个 csv 文件。因此，我创建了 zip 文件并将所有 csv 文件放入该 zip 文件中。一切正常，我可以下载我的 zip 文件并在我的本地主机上打开。我用的是windows操作系统。

这是我来自 export_csv.php 的代码.

    for($i=0; $i<$len; $i++) {
        $user_id = $array[$i];

        #get user name 
        $name = "...";

        #get all day from selected month with holidays
        $day_of_month_arr = allDay_of_month($year,$month); 

        #get user datetime

        #prepare start and finish time with holidays and weekend
        $result_arr = time_format($result, $day_of_month_arr);

        #prepare data as csv format to export as csv
        $exp = export($result_arr);

        #put each user csv file into 'Report.zip'
        #archive all csv file as zip and force download that zip file
        $zipname = 'Report.zip';
        $zip = new ZipArchive;
        $zip->open($zipname, ZipArchive::CREATE);
        $f = fopen('php://memory', 'w');
        $file_name = $name."-".$user_id.".csv";
        foreach ($exp as $arr) {
            fputcsv($f,$arr);
        }
        rewind($f);
        $zip->addFromString($file_name, stream_get_contents($f));
        //close the file
        fclose($f);

    }

    $zip->close();
    header('Content-Type: application/zip');
    header('Content-disposition: attachment; filename='.$zipname);
    header('Content-Length: ' . filesize($zipname));
    readfile($zipname);

    // remove the zip archive
    unlink($zipname);

    function export() {.......}
    function time_format() {........}
    function allDay_of_month() {......}

所以，我上传了那个脚本 export_csv.php到我的 ubuntu 服务器(生产服务器)。当我尝试从生产服务器下载此文件时，我可以下载该文件但无法再打开此 zip 文件。它显示 "......\Report.zip" is invalid" .

当我检查 php_error_logs 中的问题时，我发现了以下问题。

我认为这个错误是权限问题。但我是 ubuntu 操作系统的新手，所以我不知道如何解决它。

我非常感谢任何帮助。

更新

当我尝试从服务器下载和打开 zip 文件时，我添加了确切的错误。

似乎您的 php 服务器不允许写入您提供的路径。
您需要将运行 php 服务器的用户的写入权限添加到此路径:/opt/lampp/htdocs/project/

您应该使用 chmod linux 命令。运行 php 的 linux 用户应具有对该路径的写入权限。
