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。所以，我创建了zip文件并将所有csv文件放入该zip文件中。一切工作，我可以下载我的zip文件，并可以在我的本地主机上打开。我使用Windows操作系统。

这是我的代码export_csv.php。

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，我上传脚本export_csv.php到我的Ubuntu的服务器（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有什么问题时，我发现了下列问题。

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。

我很感激任何帮助。

更新

我添加了确切的错误，当我尝试下载并从服务器上打开zip文件。

似乎你的php服务器不允许写入你给它的路径。 您需要将运行php服务器的用户的写权限添加到此路径：/ opt/lampp/htdocs/project/

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