PhpSpreadsheet: Permissions | ZipArchive::close(): Failure to create temporary file

Question

I would like to offer an Excel-File for download with PhpSpreadsheet

Here is my code:

    require \'vendor/autoload.php\';

    use PhpOffice\\PhpSpr         


        

Answer 1

The issue was the tmp directory used by phpSpreadSheet and that was not writable by PHP process. I changed the tmp directory to upload tmp directory and now the issue is resolved. I solved the issue using

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