Membership Plugin. Php command to display subscription ID

I am building a real-estate website that displays a lot of information about each house. I want to use the membership plugin to control what information is shown to different levels of membership. For example, someone who signs up for subscription A can only see information xy on the page, whereas someone signed up to subscription B can see information xyz on the same page.

I know this will be done though if statements, but first I need to know the command to call the subscription ID.
