Re: Class question

[Thomas Munz <thomas@xxxxxxxxxxxxx>]

Use 'extends' syntax for sub classes

class A {
          var $some_var;
           var $class_B;
          function A(){
                $this->class_B = new B();
                $this->some_var=2;
          }
}

class B extends A {
          var $class_C;
          function B(){
                $this->A();
                $this->class_C = new C();
               //  $this->some_var= some_var_from_class_A; <-- $this->some_var contains the value allready
          }
}

class C extends A {
          function C(){
                $this->A();
                // $this->some_var= some_var_from_class_A; <-- $this->some_var contains the value allready
          }
}
