Description:
------------
I'm working on a simple file upload form, which works fine for small files. Then I tried to upload files larger than 'upload_max_filesize' (set to 10M) with a file about 21MB to test the error codes in $_FILES['fieldname']['error'].

When submitting the form, the $_POST and $_FILES arrays are empty, although there are other post data in the form (e.g. the session - but I switch to cookies, so I could test it).

It doesn't make a difference which file type I choose or if I add the hidden MAX_FILE_SIZE field or not.

More info:

There is no error in the apache logfiles.
'file_uploads' is 'On'
'post_max_size' is '10M'

Reproduce code:
---------------
A form similar to the one I use:

<form action="photo.php" method="POST" enctype="multipart/form-data" accept-charset="UTF-8">
<input type="file" name="photo_file" />
<input type="hidden" name="some_post_data" />
<input type="submit" />
</form>

Expected result:
----------------
Date in the $_POST array and the $_FILES array, including the correct error code.

Actual result:
--------------
Empty $_POST and $_FILES arrays.
