Patterns used with preg_replace works fine. preg_replace($pattern,
''); - from pattern to empty string and I have clean code.

It's not problem for me because I don't need code from functions/
classes like variables etc. I need only to extract functions/classes
names. So example above isn't a problem, but I understand what you
wrote, but remember that it's not a php file parser, I'm not parsing
code from methods...
