PHP File upload - rename file

[smilesinblues@hotpop.com]

Hi,
I have to allow my visitors to upload image on my site.

I am using the follwoing code to do that:

$uploaddir = 'admin/';
$uploadfile = $uploaddir . basename($_FILE S['userfile']['name']);
move_uploaded_f ile($_FILES['userfile']['tmp_name'], $uploadfile);

My problem is that I expect them to use same file name, like all of
them will be uploading files like, comments.rtf. So if there is already
one comments.rtf the file will get overwriten... so the challenge is to
rename the files to username-filename.rtf

can anybody here will take the pain to modify this code, I will be
thankful, or please guide to me some tutorial where they are dealing
with simple code and not with advanced classes.
Thank you in advane

Regards,
Jaunty Edward

Is the username unique? If so it's just

$uploadfile = $uploaddir.
$username.basen ame($_FILES['userfile']['name']);

Though you might like to add a character for neatness

$uploadfile = $uploaddir .
$username."-".basename($_FI LES['userfile']['name']);
