What's this code? [closed]

It's difficult to tell what is being asked here. This question is ambiguous, vague, incomplete, overly broad, or rhetorical and cannot be reasonably answered in its current form. For help clarifying this question so that it can be reopened, visit the help center. Closed 11 years ago.

Just for example, here's one line:

$returned = [Obfuscated]0D 03 1E 0B 19 3C 06 2E 19 1B 0C 2E 15 3E 14 25 29 08 0A 1A 1A 0F 01 ();

What exactly is it? I'm guessing it's some encoded co开发者_如何学Gode, but can someone give me information on it?

Thanks.

I think you tried to decompile an obfuscated file. Obfuscation is used to save your code if you publish it in a jar, exe etc., so nobody else can decompile and steal it.

You can obfuscate nearly all classes in your project. For more information check this wikipedia entry: http://en.wikipedia.org/wiki/Obfuscated_code
