I'm using PhpSpreadsheet to get data from an Excel XLSX file.
All works fine but, at the end, after getting data, I can't delete the file with unlink.
I have the impression that the file is open.
As I understand, \PhpOffice\PhpSpreadsheet\IOFactory::load($filename); opens the file.
But there is no \PhpOffice\PhpSpreadsheet\IOFactory::close($filename); method.
How can I delete the XLSX file?
Best,
