Sometimes when the uploaded file is bigger then MAX_FILE_SIZE (in script)the return from $_FILES['uploadedfile']['size'] is zero and sometimes it returns the right value of the file.

I have only tried whith MAX_FILE_SIZE far under what I have set in php.ini(upload_max_filesize = 2M).

Looks like it depends on how much bigger the file is then MAX_FILE_SIZE. Cant figure out the exact difference.

(the script I post is also my temporary solution for the problem)

Reproduce code:
define('MAX_FILE_SIZE', 1048);
elseif ($_FILES['uploadedfile']['size'] > MAX_FILE_SIZE or $_FILES['uploadedfile']['size'] <= 0) {
	$filesize = number_format($_FILES['uploadedfile']['size']/1024, 1).'KB';
	$uploadinfo = "<b>The image/file is proberly to bigg</b> (and maybee then returned zero)!<br /><br/ > We got this filesize from the upload file: " . $filesize ."<br /> Max acceptable size is " . $maxfs;

Expected result:
The exact filesize of the uploaded file (at least if its smaller then upload_max_filesize set in php.ini).

Actual result:
Sometimes the exact filesize of the uploaded file, sometimes zero.
