Question

So I have something like this:

class SomeClass{
    //do some stuff
}

$variable  = new SomeClass();

Now that in a php file called SomeClass.php for example, I want to in some other class called OtherClass.php do something like:

class OtherClass{
    function doSomething(){
        $variable->call_some_method();
    }
}

How would I achieve this? I have thought of global variables, but then I see frameworks like Zend doing stuff like: $this->view->what_i_want_to_pass_to_the_view = ‘hello apple sauce’;

So what’s a good way to do, essentially what I want to do.

Note: Some people are assuming I want to do global variables, this is not true. I am trying to replicate how Zend does something like $this->view in a class to send something to the view and then in the view, calls $this->view to get what was sent. I assumed this was done through globals…

I believe what you need is ‘extends’ i’ll give you an example.

class Hello {

    public function world() {
        echo 'Hello World!';
    }

}

class someClass extends Hello {

    public function doSomething() {
        $this->world();
    }
}


$obj = new someClass();
$obj->doSomething();
