php - 如何在 php 中生成带有良好渲染引号的 UTF8 CSV 文件？

Question

我想在 php 中创建一个 CSV 文件，以 UTF-8 编码，所有字符都很好地呈现（甚至重音，因为我是法国人），除了引号，它们呈现为“ '”。

谁能帮我？

这是我在 Symfony2 中的代码示例

$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);

非常感谢

Answer 1

Some pointers for you:

1. utf8_decode produces ISO-8859-1 content. Therefore your output is not UTF-8.

2. ' is the same in UTF-8, ASCII, Windows-1252 and ISO-8859-1

3. I suspect ' is coming from your CSV source.

4. 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.

这是对我有用的解决方案。我正在使用 Symfony 4.4。

headers=> 包含您的标题。
lines=> 包含你的台词。

$response = new StreamedResponse();
$response->headers->set('Content-Type', 'application/force-download');
$response->headers->set('Content-Disposition', $response->headers->makeDisposition(
    ResponseHeaderBag::DISPOSITION_ATTACHMENT,
    'export.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);
});
