How to get file info before uploading

[eluser]EyeAmN8[/eluser]
I got it!
I ended up using:

Code:

$file = $_FILES['userfile']['name'];
$ext = substr(strrchr($file, '.'), 1);

I found a lot of examples at http://cowburn.info/2008/01/13/get-file-extension-comparison/
I could probably condense it into one line, but it works
Thanks
