You just upload the file to your web server and you have the download link, if you wanna display the link just do this:
[code]<a href="URL">words</a>[/code]

Replace the URL with the download link, and the words to any words (it could be the file name).

You simply do what hackerkts said, or if you're talking about keeping the file off the public web directory (private area), then you want to force a download. Read this topic:

if your  not using a database then do this ok

<a href="file_name.zip">donload my game</a>

Just remeber i am using a non database way and the file has to be a zip file and in the same folder as the
html code.

<a href = "../downloads/program.py">Download</a>

to force downloads this is the correct method as posted link from toplay

<?PHP
ob_start();
$fname = 'http://www.example.com/test.txt';

header('HTTP/1.1 200 OK');
header('Content-Type: application/unknown');
header('Content-Disposition: attachment; filename=' . basename($fname));
header('Content-Transfer-Encoding: binary');

readfile($fname);

header('Content-Length: ' . ob_get_length());

ob_end_flush();

echo 'This will not show in browser or be in file';
?>

readfile($fname);

header('Content-Length: ' . ob_get_length());

ob_end_flush();[/color]

[code]ob_start();[/code]
Turns on 'Output buffering', meaning everything you intend to output, will be captured in an internal buffer instead of being directly outputted.

[code]header('HTTP/1.1 200 OK');
header('Content-Type: application/unknown');
header('Content-Disposition: attachment; filename=' . basename($fname));
header('Content-Transfer-Encoding: binary');[/code]
These are some HTTP/1.1 Protocol headers, you can read up on the HTTP/1.1 protcol here: [url=http://www.w3.org/Protocols/rfc2616/rfc2616.html]http://www.w3.org/Protocols/rfc2616/rfc2616.html[/url]

[code]readfile($fname);[/code]
Is a PHP function that reads a file directly into your script, binary-safe. In other words the contents of that file will be placed into your script.

[code]header('Content-Length: ' . ob_get_length());[/code]
This is another HTTP header, your sending over the length of your document, ob_get_length() returns the size of the internal output buffer in bytes.

[code]ob_end_flush();[/code]
This outputs what is currently in the internal buffer then turns off output buffering.

HTH, Zac.

When a user clicks on the link you did, then it will download the file. It's the simplest approach.

If you want to force a download to protect file location etc. then use code similar to what's provided. Please click on the link to the topic I provided and read it. It describes an approach (links.php & download.php). There's a link to a HTTP protocol book recommendation there too.

If you have the file saved locally, then use filesize() function to populate the Content-Length header and all the buffering stuff is not needed. It was used in that topic because the person had the file remotely using a full URL where filesize() doesn't work.

Good luck.
