Newbie question

[awingnut]

I have a working script, someone gave me, I am trying to modify. I have the following segment:

$upload_file = $_FILES['upload_file']['name']; 
$size = $_FILES['upload_file']['size']; 
$temp = $_FILES['upload_file']['tmp_name'];

This segment is handling a 'post' in which 'upload_file' is the passed file name. What I want to do is extract the file extension but I cannot find anything in the documentation on '$_FILES'. Trying the obvious:

$type = $_FILES['upload_file']['type'];

or:

$type = $_FILES['upload_file']['ext'];

does not work.

Can someone point me in the right direction? Thanks.

Thanks for the reply but you cheated.

I should have thought of that but I still really want to know what other information $_FILES contains and why I cannot find it in the docs.

............................................................
the common function to know the file type is $_FILES['userfile']['type'], an example of a return is 'image/gif', I am sure that you already had seen this, but I believe this is the only way....

more...
$_FILES['userfile']['name']
The original name of the file on the client machine.

$_FILES['userfile']['type']
The mime type of the file, if the browser provided this information. An example would be &quot;image/gif&quot;.

$_FILES['userfile']['size']
The size, in bytes, of the uploaded file.

$_FILES['userfile']['tmp_name']
The temporary filename of the file in which the uploaded file was stored on the server.

$_FILES['userfile']['error']
The error code associated with this file upload. ['error'] was added in PHP 4.2.0
