Foursquare API Help

I'm trying to get nearby venues. I found this url where i can just plug in lat and lon.

How do i use this URL? I tried getting the libraries from Foursquare API site, but can't get them to work.

I know i can json_decode the result on this page to get a php object, but how do i make a call and get the data to my webpage?

Thanks

$data = file_get_contents(http://MyURL/);
        $results = json_decode($data, true); //true = making it into array, not object
