I think so, I ran into the same problem, only in a different direction, I
had not attempted to upload files using PHP until recently.

I was uploading an image file to a filesystem whilst also entering the
details of the upload into a database - these included FileName, FileSize
and FileType - these were taken from $_FILES['upload']['name'],
$_FILES['upload']['size'], $_FILES['upload']['type'] - GIF and JPG were
represented as image/gif and image/jpeg as the types I uploaded, so I used
the following:

$filetype = $_FILES['upload']['type'];

// upload was the name of the upload field in the previous form.

switch($filetype) {
case 'image/jpeg':
$extention = 'jpg';
break;

case 'image/gif':
$extention = 'gif';

//( the reason for the switch is that I had a lot more image formats to
sort through )

Sorry for the slightly longwinded answer - I was going mostly by memory.

Cheers!
