      Taken from http://www.php.net/manual/de/function.eval.php#59862
     Directions:
      1. Save this snippet as decrypt.php
      2. Save encoded PHP code in coded.txt
      3. Create a blank file called decoded.txt (from shell do CHMOD 0666 decoded.txt)
      4. Execute this script (visit decrypt.php in a web browser or do php decrypt.php in the shell)
      5. Open decoded.txt, the PHP should be decrypted if not post the code on http://www.ariadoss.com/forums/web-development/lamp
