Calling method of parent class

[mkaminski]

Hello,

Say I have a class such as this..

class A
{
public function sayHello()
{
  print("hello");
}
}

class B extends A
{
public function sayHello()
{
  print("A more refined hello...perhaps bonjour?");
}
}

$object = new b();

Now $object is of type B. Calling $object->sayHello() would output "A more refined hello...perhaps bonjour?"

Now how can I call the sayHello() so that it will call the A class' sayHello() method, simply outputting "hello"? I know how to do this in Java...it would just be a simple type cast... but how can this be done in PHP 5? I want to change the type of the object, not do a parent::sayHello() in class B's sayHello() method.

Thanks!

just type
sayhello();

sorry I dont think that will do it

you can create an access method in class b

class B extends A
{
  /// your stuff

  function A_Hello()
  {
      parent::sayHello();
  }
}

For a non invasive means, if A's sayHello method doesn't involve any class variables, you can say

A::sayHello();

But the first is probaly a safer bet for anything non-trivial, and deffinitely for any method that uses class variables (instance variable).  Sometimes Global class variables will be okay.

So, the absolute safest way is the first one.  Use that if at all possible.
