Yes it's normal when you create new instance of included class,
constructor is called automatically ('new Class()'). Remember that in
constructor I can have also 'include/require' directives and it's the
main problem of that.

I had it coded in the second way that I described before (regexp) and
it work correctly, the main problem was how to choose valid regular
expressions to classes, functions, comments etc.

It's basicly to do in 3 steps:

1. Remove comments from file, they can consists faked classes and
functions e.g.
- /* class MyClass extends XXX */
- # public function test()
- // class MyClass extends XXX

2. Match with regexp class context:
- class .... { ..... }
- get class context and match functions pattern

3. Remove sweepings and here you go

My patterns (PHP preg_), they work for me now but I don't know in 100%
that they are valid - I need to test them more precisely.

Comments
------------------------
Multi line comments:
'@/\*.*?\*/@ims'

Hashed lines:
'@^[\s|\t]+#.*?$@ims'

Double slashed lines:
'@^[\s|\t]+//.*?$@ims'


Classes, functions
-------------------------
From one 'class' directive to other or to '?>':
'@^[\s|\t]+class[\s|\t]+([A-Z0-9_]+)([^{]+)?.*?(?:class|\?\>)@ism'

Probably not working for code like that (divided into few <?php ?>
directives):

------------ sample code
class MyClass extends XXX
{
}
?>

<?php
class MySecondClass...
?>
------------------------

Check if class extends XXX:
'@extends[\s|\t]+XXX@ism'

Look only for public methods:
'@^[\s|\t]+(?:function|public[\s\t]+function)[\s|\t]+([A-Z0-9_]+)@ims'

If you saw dramatic mistakes in my patterns say that :) I correct
them.
