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。一切正常，我可以下载我的zip文件，可以在我的localhost上打开。我使用的是Windows操作系统。
以下是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() {......}
因此，我将该脚本export_csv.php上传到我的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不能再打开此zip文件。它显示"......\Report.zip" is invalid"。
当我在php_error_logs中检查错误时，我发现了以下问题。

我认为这个错误是权限问题。但我是ubuntu操作系统中的新手，所以，我不知道如何解决它。
我非常感谢您的帮助。
更新
当我尝试从服务器下载并打开zip文件时，我添加了确切的错误。

好像你的php服务器不允许写入你给它的路径。 您需要向运行php服务器的用户添加写入权限到此路径：/ opt / lampp / htdocs / project /
您应该使用chmod linux命令。运行php的linux用户应具有该路径的写权限。
