How to generate UTF8 CSV file in php with well rendered quotes? - php

Question

I want to create a CSV file in php, encoded in UTF-8, all caracters are well rendered (even accents, cause I am french), except quotes, that are rendered as "'".
Can anyone help me?
Here is an example of my code, in Symfony2
$response = new Response();
$response->headers->set('Content-Type', 'text/csv');
$response->headers->set('Content-disposition', 'attachment; filename="'.$name.'.csv"');
$response->setContent(utf8_decode($csv));
$response->setStatusCode(200);
Thank's a lot

Answer 1

Some pointers for you:
utf8_decode produces ISO-8859-1 content. Therefore your output is not UTF-8.
' is the same in UTF-8, ASCII, Windows-1252 and ISO-8859-1
I suspect ' is coming from your CSV source.
If you're building the source, ensure you use UTF-8 chars. Then you don't need to convert. If you're reading from disk, make sure you know the original character set. Don't convert character sets unless you know the original character set.

Answer 2

I am using Symfony 4.4.
These are the 2 solutions that worked for me :
1. First one:
// This import is used to inject a serializer object
use Symfony\Component\Serializer\SerializerInterface;
$content = $this->serializer->serialize($csv, 'csv', [
'csv_delimiter' => ';',
'output_utf8_bom' => true,
]);
$response = new Response($content);
$response->headers->set('Cache-Control', 'no-cache');
$response->headers->set('Content-Type', 'application/force-download');
$response->headers->set('Content-Disposition', $response->headers->makeDisposition(
ResponseHeaderBag::DISPOSITION_ATTACHMENT, "$name.csv"
));
2. Second one:
headers => contains your headers.
lines => contains your lines.
$response = new StreamedResponse();
$response->headers->set('Cache-Control', 'no-cache');
$response->headers->set('Content-Type', 'application/force-download');
$response->headers->set('Content-Disposition', $response->headers->makeDisposition(
ResponseHeaderBag::DISPOSITION_ATTACHMENT,
"$name.csv"
));
$response->setCallback(function () use ($headers, $lines) {
$handle = fopen('php://output', 'w+');
// Mandatory: Use bom + "Content-Type: application/force-download" => to allow to display special characters with excel
fwrite($handle, $bom = chr(hexdec('EF')).chr(hexdec('BB')).chr(hexdec('BF')));
// headers
fputcsv($handle, $headers, ';');
// data
foreach ($lines as $line) {
fputcsv($handle, $line, ';');
}
fclose($handle);
});
