I have a CSV file containing date values. Eg. 3/1/2015
But with my current code
$rowData[$i][0][6] = date('Y-m-d', PHPExcel_Shared_Date::ExcelToPHP($upper[0][6]));
it reads it as 2036-02-09.
I know PHPExcel is best used with xls and xlsx, but my boss tells me to use a csv file for a file upload event. How can i get the correct date?
