    It's been obfuscated. In other words the author made it hard to read - for a reason.

    It may be copyrighted code for instance.
    See my new CodingForums Blog: http://www.codingforums.com/blogs/tangoforce/

    Many useful explanations and tips including: Cannot modify headers - already sent, The IE if (isset($_POST['submit'])) bug explained, unexpected T_CONSTANT_ENCAPSED_STRING, debugging tips and much more!
