Image Mime Type Problem

[chunk1978]

hi. i have this mime-type array in my php upload script... but my mime type for photoshop files isn't working. what's wrong with this?

# -=-=-=- Allowed File Extensions:  .TIF / .PSD / .JPG / .JPEG / .JPE / .PNG

$mimetypes = array
(
'image/tiff',
'image/vnd.adobe.photoshop',
'image/jpeg',
'image/png',
);

Try

print($_FILES['whateverYouCalledIt']['type'];
exit;

To see why it's not matching.

[EDIT: Incidentally, if you made the array keys the accepted types, your script would execute a tiny bit faster as it could use a reference instead of have to loop through the entire array to find a matching MIME type.

E.g.:

$mimetypes = array
(
'image/tiff', => true,
'image/vnd.adobe.photoshop', => true,
'image/jpeg', => true,
'image/png', => true
);

if(! $mimetypes[$_FILES['whateverYouCalledIt']['type']]) {
    header('Location:  somepage.php?message=MIME_TYPE_MISMATCH');
    exit;
}

The other advantage of doing this is that if you wanted to temporarily disable support for a particular mime-type, you could just set its value to false instead of deleting it or commenting it out).
