How Kohana make chain between static and non-static?

Question

I'm not good in PHP and newbie in Kohana.

I'm very interesting how Kohana makes this structure: Request::current()->controller() . We call static method and then call non-static method.

How I can organise similar structure?

Answer 1

Request::current() will return an object, and you execute the controller() method on that object.

I understand you're confused with the use of static and non-static at the same time. It isn't confusing at all. Given these two classes:

static class StaticClass
{
    public function GetSomeObject
    {
        return new SomeObject();
    }
}

class SomeObject
{
    public function DoSomething()
    {
        // Do something
    }
}

You can then initialize a SomeObject yourself, and execute its method:

$someObject = new SomeObject();
$someObject->DoSomething();

But it some cases this isn't desirable. I can imagine the StaticClass being some kind of repository (a singleton or factory for example), managing your SomeObject instances. You have to retreive all SomeObject s from the StaticClass. In this example this is done like this:

$someObject = StaticClass::GetSomeObject();

You can then again call the method:

$someObject->DoSomething();

The latter two can be written at once like this:

StaticClass::GetSomeObject()->DoSomething();
