[SOLVED] Interface with private methods

[radalin]

Hi,

 

I'm trying to create an interface with private methods. But when I try to run the file, I get an error:

 

Access type for interface method myInterface::prvfnc() must be omitted in c:\htdocs\file.php on line 12

 

My interface is like this:

 

interface myInterface {
  private function prvfnc();
}

 

and my class is like:

 

class myClass implements myInterface {
  private function prvfnc() {
    echo "private function call";
  }
}

 

Is private methods are not allowed in PHP interfaces?

 

Thanks for your time.

i don't think interfaces define if a method is public/protected/private. that is something that the class implementing it does.

That should be fine.

 

What php version are you using?

The problem is, if I do not define public/private/protected in the interface, it takes the access level of the method as public and in class if I define it as a private function I get an error like this:

 

Access level to myClass::prvfnc() must be public (as in class myInterface) in C:\htdocs\file.php on line 12

 

Is it a bug perhaps?

 

 

Edit: PHP version is 5.2.6

Which is line 12?

All methods in an interface must be public.

 

It wouldn't much of an interface otherwise, would it (stop and think for a sec)?

[radalin]

Well, honestly that really makes sense Why to define a function which you can never be able to call...

 

But how I'm using the interface is to define which functions must have a class and it looks like more of a blue print than a real interface.

 

But you are quite right about that

If you want to ensure child classes implement a common method, but not expose it outside the hierarchy, use an abstract protected method.

[radalin]

Yes I guess that was the way to use it.

 

Thanks for your time.

Hehe, I didn't even think about it that way. Still, didn't think it would throw an error either.
