<?
function send_file($name) {
ob_end_clean();
$path = "/directory/path/".$name;
if (!is_file($path) or connection_status()!=0) return(FALSE);
header("Cache-Control: no-store, no-cache, must-revalidate");

And now how to use it...
<?php
session_start();
//Validate the user
if($_SESSION[login] == 1){
//Close the session to allow for header() to be sent
session_write_close();
if(!send_file("testfile.zip")) {
die ("file transfer failed");
} else {
//Log the download
}
}else{
echo "Not logged in";
}
?>
This lets a user download a file while still being able to browse your site.
