How do I pass two items of data from the Postman Application to PHP so that the data is obtained using file_get_content

I want to pass two items of data to a php routine using the Postman application, such that my PHP code obtains the values using the command:

$data = json_decode(file_get_contents(‘php://input’), true);

In the Postman app I have tried various settings, but I am unsuccessfully getting the data. Below is a screenshot of my last attempt. Any help would be greatly appreciated.

Below is a screenshot of my settings:
