I’m working on a PHP script that creates a .csv file from some data.
Unfortunately, in Excel Umlauts are not displayed properly: Löl
becomes Löl
(this is just in Excel, in Apple’s Numbers, Atom and Textedit everything looks fine).
I have tried hundreds of functions to try and get the encoding right (see the commented functions below). Could someone please tell me what I’m doing wrong?
$rows = json_decode('[["Löl"]]'); foreach($rows as $key_row => $row) { foreach($row as $key_cell => $cell) { // $rows[$key_row][$key_cell] = utf8_decode($cell); // $rows[$key_row][$key_cell] = iconv('UTF-8', 'Windows-1252', $cell); // $rows[$key_row][$key_cell] = mb_convert_encoding($cell, 'UTF-16LE', 'UTF-8'); // iconv('UTF-8', 'Windows-1252', $rows[$key_row][$key_cell]); // mb_convert_encoding($rows[$key_row][$key_cell], 'UTF-16LE', 'UTF-8'); } } $temp = fopen('php://memory', 'w'); foreach($rows as $row) { fputcsv($temp, $row, ';'); } fseek($temp, 0); header('Content-Type: application/csv'); header('Content-Disposition: attachment; filename="test.csv";'); fpassthru($temp);

The following conversion to UTF-8 BOM
worked:
foreach($rows as $key_row => $row) { foreach($row as $key_cell => $cell) { $rows[$key_row][$key_cell] = chr(239) . chr(187) . chr(191) . $cell; } }
Thanks for everybody who chimed in 🙂
