timeout-Notice: Use of undefined constant SOCKET_EAGAIN - assume

I have pasted the 100% PHP Uploader folder on my server its working for all files except large files, images. For the size 4MB,or more is giving following notice:

Notice: Use of undefined constant SOCKET_EAGAIN - assumed 'SOCKET_EAGAIN' in C:\xampp\htdocs\PHPCLASSES\up-man-2011-11-03\uploadmanager.class.php on line 162

I think you're using an older version of the socket extension library.
You could try to upgrade it or:

add the following line to your code (just let it execute once)

if (!defined('SOCKET_EAGAIN')) define('SOCKET_EAGAIN', 35);

On my system the constant is defined as 35.
Other resources on the internet state it should be 11.
