I have downloaded an open source application. However, 2 of the files are decrypted. I really would love to get readable.
Here is the first file that I would like to get decoded:
<?php

I reversed engineered the code. But the code has defections that prevents it from running correctly (You can run the script directly to see for yourself!). But I managed to clear the crippled code and repair some parts by myself. This is the decoded form:
