write utf-8 characters to file with fputcsv in php

Question

I want to try write Persian character in CSV file in PHP, I am using fputcsv function but how can write UTF-8 character to CSV file with fputcsv?

Part of my code:

$df = fopen($filepath, 'w');
fputcsv($df, array($coupon->code, $discount->label));

Answer 1

Try this:

$df = fopen($filepath, 'w');
fprintf($df, chr(0xEF).chr(0xBB).chr(0xBF));
fputcsv($df, array($coupon->code, $discount->label));

the line fprintf($df, chr(0xEF).chr(0xBB).chr(0xBF)); writes file header for correct encoding.

Answer 2

Try this also:

$df = fopen($filepath, 'w');
$array = array($coupon->code, $discount->label);
$array = array_map("utf8_decode", $array);
fputcsv($df, $array);

Answer 3

If you want make a UTF-8 file for excel, use this simple solution:

$fp = fopen($filename, 'w');

//add BOM to fix UTF-8 in Excel 
fputs($fp, $bom =( chr(0xEF) . chr(0xBB) . chr(0xBF) ));
