[php] Packer, Obfuscater, Encoder

EDIT 10/19/2010: I noticed that this is getting a lot of attention. I haven't touched this in ages, and it ISN'T made for obfuscating non-class files. On top of that, it has many, many, many, problems! I DO NOT RECOMMEND IT'S USAGE! Since this, I've had a much larger, true obfuscater on the way. So once again, I do not support this anymore!

Will some people here take this for a spin. I've only tested it with my stuff. I need to know if it works for more than just my code. Oh, and this is version 0.8. It isn't perfect, and probably has several bugs that I don't know about.
-----------------------------

Here's the code.

Rules:
* Passkeys do not work
* Maximum Variables Amount = 702
* # inside quotes cause issues.
* <?php and ?> need to not be in the inserted data.

The reason I'm not running this live and giving the source code is because there are probably some leaks in it. That's because of my sloppy programming when I first started it trying to prevent errors I ended up with more. However, I think I've gotten rid of a good load of the errors.
