How this Facebook API Program Capture Visitors Name and Email without Permission

Question

I wonder How this Facebook API Program Capture Visitors Name and Email without Permission. I visited a Facebook page today and found that my name and email automateically appear when I click on the post image. I guess they are doing it with the latest Facebook SDK.

This is the post I am referring to.

This is the page about their API Script.

Can anyone tell me where I can setup the same using PHP. I could not locate any information in Facebooks developer page. Highly appreciate your feedback.

Ishaq.
