Writer/BaseWriter.php: failed to open stream: Permission denied

[magicua]

Hello.

This is a bug report

I am getting the following error:
[2021-11-05 15:18:37] production.ERROR: fopen(/var/www/applications/.../storage/framework/laravel-excel/laravel-excel-scZOjOuy25S7MOmMyXnRYzntkoCoLJxZ.xlsx): failed to open stream: Permission denied {"exception":"[object] (ErrorException(code: 0): fopen(/var/www/applications/.../storage/framework/laravel-excel/laravel-excel-scZOjOuy25S7MOmMyXnRYzntkoCoLJxZ.xlsx): failed to open stream: Permission denied at /var/www/applications/.../vendor/phpoffice/phpspreadsheet/src/PhpSpreadsheet/Writer/BaseWriter.php:123)
[stacktrace]
#0 [internal function]: Illuminate\Foundation\Bootstrap\HandleExceptions->handleError(2, 'fopen(/var/www/...', '/var/www/applic...', 123, Array)
#1 /var/www/applications/.../vendor/phpoffice/phpspreadsheet/src/PhpSpreadsheet/Writer/BaseWriter.php(123): fopen('/var/www/applic...', 'wb+')

but the rights to the file are correct:
-rw-r--r-- 1 www-data www-data 0 Nov 5 13:15 /var/www/applications/.../storage/framework/laravel-excel/laravel-excel-scZOjOuy25S7MOmMyXnRYzntkoCoLJxZ.xlsx

probably the problem is in the file phpoffice/phpspreadsheet/src/PhpSpreadsheet/Writer/BaseWriter.php in the line 118
$mode = 'wb+';

I think it is necessary to write:
$mode = 'w+b';

because the documentation states:
https://www.php.net/manual/en/function.fopen.php
To use these flags, specify either 'b' or 't' as the last character of the mode parameter.

Facing the same issue on Ubuntu 20.04 server, this solution worked for me:

PR 2657, which I hope will resolve this problem, was just merged. If you have a way to test against master, please do so.

No update in 4 months. I believe it is fixed. Closing.
