问题
I am trying to export some data to an excel sheet using fputcsv on PHP. I know that .csv files do not support style. If there any way I can add style to that file by saving the file as .xls?
回答1:
CSV and XLS formats are totally different. So if you want to add style, you have to create an XLS file (and forget fputcsv :/ ).
Have a look to PhpExcel.
