hey,

i was just looking at the header function on php.net and saw this

PHP Code:

<?php
// We'll be outputting a PDF
header('Content-type: application/pdf');

// It will be called downloaded.pdf
header('Content-Disposition: attachment; filename="downloaded.pdf"');

// The PDF source is in original.pdf
readfile('original.pdf');
?>

</SPAN>

could this be used like one of those download things so users dont know the actual location of a file? and have it so the new name is like a random string?.

Dan.

Yes. There is nothing there that would send out the original file name original.pdf.

Although most people usually name the original file something random, and something obvious for the downloaded file so the users know what the file is later on.

is this how download sites have the thing like where u have a page open and then it pops up to download after like 10 seconds?

It can be. You can put an invisible iframe on an existing page (such as the download page) and call your download script in the iframe. There is usually a short delay, and that is just general Internet latency, the server finding the file, etc. If there is a longer delay, like 10 seconds, I think that is because those download scripts are loading the entire file into the script, waiting until it's completely loaded, then outputing it. I've only dealt with small-medium files with readfile() though.

no im refering to the ones like which have a countdown one purpose no matter the file, it waits and then pops up
