I have an array with some keys and I want to get the array values according to the array keys where the keys are in a string.

Example:

```
$arr = array(
        "COV" => "Comilla Victorians",
        "RK"  => "Rajshaji Kings"
    );

$str = "COV-RK";

```

Now I want to show `Comilla Victorians VS Rajshaji Kings`.

I can do it using some custom looping, But I need some smart coding here and looks your attention. I think there are some ways to make it with array functions that I don't know.
