I know your array section is coming later but it’s a pretty simple. Please review the following:

 array(
                    "red" => "apples",
                    "yellow" => "bananas",
                    "orange" => "oranges"
                    ),
            "veggies" => array(
                    "orange" => "carrots",
                    "brown" => "potatoes",
                    "green" => "peas"
                    )
        );

echo $array["fruits"]["orange"] . "" . $array["veggies"]["orange"];
?>

As you can see- arrays can be fun!
