I have a PHP app that creates a CSV file which is forced to download using headers. Here’s the relevant part of the code:
header('Content-Type: application/csv');
header("Content-length: " . filesize($NewFile));
header('Content-Disposition: attachment; filename="' . $FileName . '"');
echo $content;
exit();
What I’d like to do is redirect users to a new page after the file is built and the download prompt is sent. Just adding header("Location: /newpage") to the end didn’t work, expectedly, so I’m not sure how to rig this up.

I don’t think this can be done – although I am not 100% sure.
The common thing (e.g. in popular download sites) is the reverse: first you go to the after page and then the download starts.
So redirect your users to the final page that (among other things) says:
Your download should start automatically. If not click [a href="create_csv.php"]here[/a].
As about initiating the download (e.g. automatically calling create_csv.php) you have many options:
- HTML:
[meta http-equiv="refresh" content="5;url=http://site/create_csv.php"] - Javascript:
location.href = 'http://site/create_csv.php'; - iframe:
[iframe src="create_csv.php"][/iframe]
