ignore_user_abort() and readfile

[poehler]

Hi all. If I'm sending a large file, say, a zip file to the browser though use of
header("Content-type: application/zip");
readfile("bigfile.zip"),

and the user clicks the "cancel" button during the download, how can I catch that event and "clean up"? - in this by clean up I mean deleting the large file.

I tried calling ignore_user_abort(), but the file still doesn't get deleted after a cancel. I'm not sure what becomes of a readfile() if it gets "canceled" by the browser. Can someone enlighten me?

thanks kindly,
Paul

AFAIK, calling ingnore_user_abort() without any parms will only return the current value of the setting, not change your script's bevior. If you want to change your script to actually ignore aborts, call the function with true for an argument.

For the purposes of always deleting the file, regardless of whether they downloaded it all or not, I recommend using register_shutdown_function() instead.
