I have a file csv with code: 
我有一个带代码的csv文件：

$fp = fopen($file, 'w');
foreach ($excel as $fields) {
fputcsv($fp, $fields);
}
// download file when click button: //单击按钮时下载文件：
if ($this->request->getPost('cvs')) { {
if (file_exists($file)) {
header('Content-Type: text/csv');
header('Content-Disposition: attachment; filename=' . ($file));
header('Pragma: no-cache');
readfile('/var/www/admin/backend/public/' . $file);
// OR readfile($file);
}
}
Data in file.csv (file.csv in publuc folder): file.csv中的数据（publuc文件夹中的file.csv）：

a bit late but I think everyone missed the phalcon tag. 有点晚了，但我想每个人都错过了phalcon标签。 what is missing is the 所缺少的是
$this->view->setRenderLevel(\Phalcon\Mvc\View::LEVEL_NO_RENDER);

Here is my way to handle this. 这是我的处理方法。
$this->response->resetHeaders();
$this->response->setHeader('Content-Type', 'application/csv');
$this->response->setHeader('Content-Disposition', 'attachment; filename='.$fileName);
$this->response->setContent($content);
return $this->response;
$content - For me it is a string made from array but you can also use file_get_contents() $ content-对我来说，这是一个由数组组成的字符串，但您也可以使用file_get_contents（）

I would need more information to answer with certainty, but it sounds like the browser is simply configured to save this type of download as html. 我需要更多信息来肯定地回答，但这听起来像只是将浏览器配置为将这种类型的下载另存为html。 Try using another browser or even better use an FTP client to get the file so the browser is not a factor. 尝试使用其他浏览器，或者甚至更好地使用FTP客户端来获取文件，因此浏览器不是一个因素。
If you would like to continue to use the browser, try doing the following instead of just clicking the link: 如果您想继续使用浏览器，请尝试执行以下操作，而不只是单击链接：
Put the mouse over the link and then right click. 将鼠标放在链接上，然后右键单击。 If you have an option to "save as" save the file as a .csv. 如果您可以选择“另存为”，则将文件另存为.csv。 It may automatically select .csv for you if you choose save as. 如果选择另存为，它将自动为您选择.csv。

use content/Type as, 将内容/类型用作
header('Content-Type: application/csv');
instead of header('Content-Type: text/csv'); 而不是header('Content-Type: text/csv');

You can also use the below two lines
header("Content-type: text/x-csv");
header("Content-type: application/csv");
If you want to set any particular file name to the download file then you can add
header("Content-Disposition: attachment; filename=dates_for_".date('dMy').".csv");
