要设置 codeigniter 以下载 CSV 格式，请使用以下代码。

function _push_file($path, $name)
{
  // make sure it's a file before doing anything!
  if(is_file($path))
  {
    // required for IE
    if(ini_get('zlib.output_compression')) { ini_set('zlib.output_compression', 'Off'); }

    // get the file mime type using the file extension
    $this->load->helper('file');

    $mime = get_mime_by_extension($path);

    // Build the headers to push out the file properly.
    header('Pragma: public');     // required
    header('Expires: 0');         // no cache
    header('Cache-Control: must-revalidate, post-check=0, pre-check=0');
    header('Last-Modified: '.gmdate ('D, d M Y H:i:s', filemtime ($path)).' GMT');
    header('Cache-Control: private',false);
    header('Content-Type: '.$mime);  // Add the mime type from Code igniter.
    header('Content-Disposition: attachment; filename="'.basename($name).'"');  // Add the file name
    header('Content-Transfer-Encoding: binary');
    header('Content-Length: '.filesize($path)); // provide file size
    header('Connection: close');
    readfile($path); // push it out
    exit();
}

我不知道我是否理解正确，但如果您的问题是您希望 Excel 将 CSV 文件识别为 UTF-8 编码，则必须添加UTF-8 BOM 到您的文件。只需在 CSV 输出前加上

chr(239) . chr(187) . chr(191) // xEF xBB xBF

例如：

$data = chr(239) . chr(187) . chr(191) . $this->dbutil->csv_from_result($result, $delimiter, $newline);

如果您的问题与强制下载有关，也许会有所帮助。

Answer 3

将你的force_download从

force_download($filename, $data);

为此：

force_download($filename, "\xEF\xBB\xBF" . $data);

这使得输出为 UTF-8 + BOM，因此它被 MS 识别 Excel
