Question

我有一个关于在列表中显示根目录的所有文件的项目，用户可以浏览文件目录，按名称搜索文件，使用按钮downloadAll他可以下载当前列表中的所有文件。要使downloadAll按钮工作，我使用downloadAll.php代码，通过获取当前目录可以创建一个zip文件并自动下载它。它在Windows中工作正常。我试图在linux上运行相同的项目，但在这种情况下，它会下载一个空的压缩文件。此外，当我尝试打开它时，会显示以下消息：

Archive:  /tmp/archived_name.zip
[/tmp/archived_name.zip]
  End-of-central-directory signature not found.  Either this file is not
  a zipfile, or it constitutes one disk of a multi-part archive.  In the
  latter case the central directory and zipfile comment will be found on
  the last disk(s) of this archive.
zipinfo:  cannot find zipfile directory in one of /tmp/archived_name.zip or
          /tmp/archived_name.zip.zip, and cannot find /tmp/archived_name.zip.ZIP, period.

downloadZip.php：

<?php
if ((isset($_GET['currentdirectory'])) && ($_GET['currentdirectory']!="")){
    $the_folder = $_GET['currentdirectory']; 
}
else {
    $the_folder = "/var/www/my_project";
}

    $the_folder1 = $the_folder;

$zip_file_name = 'archived_name.zip';

$download_file= true;

class FlxZipArchive extends ZipArchive {

    public function addDir($location, $name) {
        $this->addEmptyDir(str_replace("./","",$name));

        $this->addDirDo($location, str_replace("./","",$name));
    } 

    private function addDirDo($location, $name) {
        $name .= '/';
        $location .= '/';

        $dir = opendir ($location);
        while ($file = readdir($dir))
        {
            if ($file == '.' || $file == '..') continue;

            $do = (filetype( $location . $file) == 'dir') ? 'addDir' : 'addFile';

                $this->$do($location . $file, str_replace("./","",$name) . $file);
        }
    } 
}

$za = new FlxZipArchive;
$res = $za->open($zip_file_name, ZipArchive::CREATE);
if($res === TRUE) 
{
    $za->addDir($the_folder1, basename($the_folder1));
    $za->close();
}
else  { echo 'Could not create a zip archive';}

if ($download_file)
{
    ob_get_clean();
    header("Pragma: public");
    header("Expires: 0");
    header("Cache-Control: must-revalidate, post-check=0, pre-check=0");
    header("Cache-Control: private", false);
    header("Content-Type: application/zip");
    header("Content-Disposition: attachment; filename=" . basename($zip_file_name) . ";" );
    header("Content-Transfer-Encoding: binary");
    header("Content-Length: " . filesize($zip_file_name));
    readfile($zip_file_name);
}
unlink("archived_name.zip");
?>

您可能在其他地方发生错误。尝试将$download_file设置为false并设置error_reporting(E_ALL)以查看是否有任何错误。如果这不起作用，请尝试查看Web服务器错误日志。对于apache，默认为/var/log/apache2/error.log。

php代码压缩和自动下载文件。适用于Windows，但不适用于Ubuntu
