/**
* PHPScrambler by Sven Kirsim?e
* LLC Accuro
* <a href="mailto:sven.kirsimae@accuro.ee">sven.kirsimae@accuro.ee</a>
* Estonia
*
* THIS CODE IS (OF COURSE) FREE TO USE :) !
*
* Simple php file source scrambler.
* Simply removes comments and newlines
* from php files making them hard to read :)
* but keeps them working.
*
* When using PHPScramble always keep the original
* PHP code because scrambled code can be hard
* to read even for the code creator or at least
* for the case if the scrambler will not work :| !
*
* When code is scrambled, just rename the scrambled
* file as the original one (remove 'cr' extension)
* and take it in use.
*
* !!!!!!! SCRAMBLE FILE FORMAT !!!!!!!
*
* All the comment has to be on their own line!
*
* WRONG WAY OF COMMENTING:
* if (doFunction()){ //This 'if' does that
* ...
* } //if
*
* HAS TO BE:
* //This if does that
* if (doFunction()){
* ...
* }
* // if
*
* If this type of commenting not followed, the
* scrambler can scramble the file, but the php code
* may fail to work!
*
* In order to change comments into the right
* ones, simply make search for '//'
* in php file and move [Enter] all '//' styled
* comments to new line.
*
* !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
