PhpSpreadsheet：权限 | ZipArchive::close(): 创建临时文件失败

Question

我想提供一个 Excel- 文件供 PhpSpreadsheet 下载

这是我的代码：

    require 'vendor/autoload.php';

    use PhpOffice\PhpSpreadsheet\Spreadsheet;
    use PhpOffice\PhpSpreadsheet\Writer\Xlsx;

    $spreadsheet = new Spreadsheet();
    $sheet = $spreadsheet->getActiveSheet();
    $sheet->setCellValue('A1', 'Hello World !');

    $writer = new Xlsx($spreadsheet);
    $writer = \PhpOffice\PhpSpreadsheet\IOFactory::createWriter($spreadsheet, 'Xlsx');

    header('Content-Type: application/vnd.ms-excel');
    header('Content-Disposition: attachment; filename="hello_world.xlsx"');
    $writer->save("php://output");

我收到以下错误消息：

    PHP Warning:  ZipArchive::close(): Failure to create temporary file: No such file or directory in /Users/sg/GitWorkingCopies/xxx1/xxx2/library/phpoffice/phpspreadsheet/src/PhpSpreadsheet/Writer/Xlsx.php on line 374
    PHP Fatal error:  Uncaught exception 'PhpOffice\PhpSpreadsheet\Writer\Exception' with message 'Could not close zip file php://output.' in /Users/sg/GitWorkingCopies/xxx1/xxx2/library/phpoffice/phpspreadsheet/src/PhpSpreadsheet/Writer/Xlsx.php:375

dokumentation of PHPSpreadsheet 说：

\PhpOffice\PhpSpreadsheet\Writer\Xlsx uses temporary storage when writing to php://output. By default, temporary files are stored in the script's working directory. When there is no access, it falls back to the operating system's temporary files location.

upload_tmp_dir是：/Applications/XAMPP/xamppfiles/temp/

我必须检查哪些文件夹权限？或者是什么导致了问题？

Answer 1

PHP 中目录写入的一般规则：

必须存在,

可由PHP进程写入,

open_basedirphp.ini指令允许

因此，在 $writer->save() 方法中设置一些文件路径作为参数，并检查是否满足这 3 个规则。

如果您只想在 $writer->save() 方法中使用 php://output 或 php://stdout 值，请检查以下规则：

1) sys_get_temp_dir() 函数返回的目录。在 Windows sys_get_temp_dir() 默认情况下 returns 当前 OS 用户的临时目录。该值可以通过 sys_temp_dir php.ini 指令更改。

或

2) upload_tmp_dir php.ini 指令返回的目录。默认情况下，$useUploadTempDirectory 具有 false 值。要将其值设置为 true，请在保存文件之前在代码中添加此行：

\PhpOffice\PhpSpreadsheet\Shared\File::setUseUploadTempDirectory(true);

这里是负责选择保存路径的代码：

来自\PhpOffice\PhpSpreadsheet\Writer\Xlsx::save方法（source）：

// If $pFilename is php://output or php://stdout, make it a temporary file...
$originalFilename = $pFilename;
if (strtolower($pFilename) == 'php://output' || strtolower($pFilename) == 'php://stdout') {
    $pFilename = @tempnam(File::sysGetTempDir(), 'phpxltmp');
    if ($pFilename == '') {
        $pFilename = $originalFilename;
    }
}

来自\PhpOffice\PhpSpreadsheet\SharedFile::sysGetTempDir方法（source）：

/**
 * Get the systems temporary directory.
 *
 * @return string
 */
public static function sysGetTempDir()
{
    if (self::$useUploadTempDirectory) {
        //  use upload-directory when defined to allow 
        // running on environments having very restricted open_basedir configs
        if (ini_get('upload_tmp_dir') !== false) {
            if ($temp = ini_get('upload_tmp_dir')) {
                if (file_exists($temp)) {
                    return realpath($temp);
                }
            }
        }
    }
    return realpath(sys_get_temp_dir());
}

Answer 2

我不知道您的代码是否来自包含的文件，但我遇到了类似的问题。我尝试使用 __DIR__ 常量并且有效，我的代码如下所示：

$filepath = __DIR__ . "/reports/${filename}_".date("Ymd_Gis").".xlsx";
$writer = new \PhpOffice\PhpSpreadsheet\Writer\Xlsx($spreadsheet);
$writer->save($filepath);

问题出在 phpSpreadSheet 使用的 tmp 目录，PHP 进程无法写入该目录。我将 tmp 目录更改为上传 tmp 目录，现在问题已解决。我使用

解决了这个问题

\PhpOffice\PhpSpreadsheet\Shared\File::setUseUploadTempDirectory(true);
