Obfuscation
Simply put its jumbling up your code (in a pattern <---- this has a weakness also but hey I still said it also :P )
anyway lets keep the newbies and the lazy bums at bay for the least of the part.
So a Wikipedia explanation is as such: In software development, obfuscation is the deliberate act of creating obfuscated code, i.e. source or machine code that is difficult for humans to understand.
Programmers may deliberately obfuscate code to conceal its purpose (security through obscurity) or its logic, in order to prevent tampering, deter reverse engineering, or as a puzzle or recreational challenge for someone reading the source code.

1. Manual
2. Automated
(well mainly i use manual to decode)
Say we have this piece of code
<?php echo '<p>Hello World</p>'; ?>
and we have this

Well truth is all of the following pieces of PHP codes are the same, heres where i did a quick automated obfuscation FOPO and with this we can do PHP obfuscation . you can also do other languages just a matter of searching.
Now this is not 100% full proof also another issue is that some of this methods make it hard for servers/language virtual machines(java) to understand very heavily obfuscated code.
other issues on java are lack of proper reflection programming .
Any way with this method think of how many newbies even leet* hackers and reverse engineers go like huh say what?
anyway will teach decoding all this manually later
back to code.
sawa,
Wazi.
