How to download a temporary file

Question

I\'m trying to create a short PHP script that takes a JSON string, converts it to CSV format (using fputcsv), and makes that CSV available as a downloaded .csv file

Answer 1

Note that tmpfile() returns a file handle, but all the functions you have need a file path (i.e a string), not a handle - notably basename, filesize, and readfile. So none of those function calls will work correctly. Also basename won't return a file extension either. Just call it whatever you want, i.e

'Content-Disposition: attachment; filename=data.csv'

As @Joshua Burns also says, make sure you're passing in an array to fputcsv or use the assoc parameter.
