I would like to add the Spreadsheet library to my project. I am using Netbeans that are connected to my shared hosting and when I am saving a file, it’s uploading automatically to the server. I can’t add Composer to the server while it is a shared hosting package. When I instantiate the Spreadsheet class:
$spreadsheet = new Spreadsheet(); $sheet = $spreadsheet->getActiveSheet(); $sheet->setCellValue('A1', 'Hello World !'); $writer = new Xlsx($spreadsheet); $writer->save('hello world.xlsx');
I receive that error:
PHP Fatal error: Call to undefined method Spreadsheet::getActiveSheet()
Somebody could tell me any solution to work with?
