I am facing one issue with PHP spreadsheet reader https://github.com/nuovo/spreadsheet-reader , it is reading all formats file except .xlsx , in case of .xlsx script was not running
require($docroot.'/inc/filereader/excel_reader2.php');
require($docroot.'/inc/SpreadsheetReader.inc.php');
$Spreadsheet = new SpreadsheetReader("filepath");
When i am executing php script at my localhost, SpreadsheetReader reading .xlsx file and returning desired result, but when i am trying to run same code on some server then it is only executing for(.csv,.xls,.txt) but not for .xlsx.
I have already checked folder and file permissions for above issue at server.
What may be problem here?
