[SOLVED] delete temp file on server

[jmurch]

I am using the following to generate an xml doc to the users browser:

 

$fp = fopen("document.xml", 'w+');

$str = ($xml_frame->Fields('top_xml').$content->Fields('xml').$content->Fields('xml').$xml_frame->Fields('bottom_xml'));

fwrite($fp, $str);

fclose($fp);

header( 'Location: https://www.website.com/document.xml') ;

 

I would like to delete 'document.xml' after it has been loaded to the user's browser but unlinking the file kills it before it loads and sleep hangs everything. I there a way to detect when it's finished downloading to the user?

 

Thanks
