Answer 1

For example:

$json = file_get_contents("http://graph.facebook.com/730350233684840/comments?limit=2500&access_token=[your-access-token]");

The most basic Access Token is an App Access Token, you can create one like this:

$appAccesstoken = $appId . '|' . $appSecret;

Depending on the resource, you may need a User or Page Token though. For that, you will have to authorize the User and it gets a lot more complicated.
