Facebook-PHP-SDK / Find out if user LIKES or NOT.

Hi There. I'm looking for somebody who is familiar with the ! NEWEST ! version of Facebook php-sdk. I need a php page that tells me if a user already likes my fan page (just echo a "Yes" or "No". But this is going to be used on my website, not in a Facebook tab. Here is an example: (but I tried this and it either didn't work because it was made for an older vernon of the fb-sdk, I did something wrong in the Facebook app center, or it only works in tabs. All I need is a php file (around 30 lines of code) so that i get an answer from Facebook. I'm coding everything else myself. And it would have to be ready in 2 or 3 hours tops. So PLEASE only answer if you are REALLY familiar with [login to view URL] It should be around 30 lines of code - budget is 30.
