Ajax调用后强制下载

I have a php script that is waiting for ajax calls at

www.mydomain.com/file.php

The ajax call contains some variables, that the file.php will use to generate some csv results,

Would it be possible for the user to be able to download the csv content produced by file.php without having to save it somewhere on the server and stuff?

I don't want to redirect the user to any other page either, I want them to click a button then see the download dialog, and let them download the csv file.

    Sure, in the PHP file before you output anything, set the content-type to something the browser will download:

    header("Content-Type: application/octet-stream");
    

    Additionally this is a good practice to include too (and lets you suggest a file name):

    header("Content-Disposition: attachment; filename=somefile.csv;");
    

    Depending on the browser sometimes only the later is needed, but I generally use both to make sure.
