This is my favourite download-script, it works with files bigger than 10 MB on Apache 1.3 (or higher). I added the cache control to open also text files and others (without saving). Try the demo.

<?php
// ver. 1.04 - added an example how to use this script with the filename from a query string
// ver. 1.03 - moved the disposition header into the switch because the attachement attibute is sometimes needed
// ver. 1.02 - use pathinfo() to get the fileinformation (extesnion) now
// ver. 1.01 - Added the stringconv. to handle also extensions with caps

// place this code inside a php file and call it f.e. "download.php"
$path = $_SERVER['DOCUMENT_ROOT']."/path2file/"; // play with the path if the document root does noet exist
$fullPath = $path.$_GET['downnload_file'];

if ($fd = fopen ($fullPath, "r")) {
$fsize = filesize($fullPath);
$path_parts = pathinfo($fullPath);
$ext = strtolower($path_parts["extension"]);
switch ($ext) {
case "pdf":
header("Content-type: application/pdf"); // add here more headers for diff. extensions
header("Content-Disposition: attachment; filename=\"".$path_parts["basename"]."\""); // use 'attachement' to force a download
break;
default;
header("Content-type: application/octet-stream");
header("Content-Disposition: filename=\"".$path_parts["basename"]."\"");
}
header("Content-length: $fsize");
header("Cache-control: private"); //use this to open files directly
while(!feof($fd)) {
$buffer = fread($fd, 2048);
echo $buffer;
}
}
fclose ($fd);
exit;
