Re: Class question

What does "$this->A(); "" do ?(in constructor of class B) does it make another instance of class A, and if not why do I have to parse vars to the A constructor ($this->A($var1,$var2))?. I dont think that is what I want. A can have many instances of B. B can have many instances of C.

                                                     A
                           B               B               B              B
                     CCCC         CCCC      CCCC        CCCC

Should not a instanse(object) of class B bee able to request av var of the calling object (class A)? Sorry about this stupid questions, I'm not a coder. Thomas Munz wrote:

Use 'extends' syntax for sub classes class A {

} How can class B and C get the value of $some_var_class_A without using "$this->class_B = new B($some_var);" roger helgesen
