Here is the technique to get the detail of the Facebook page with Graph API and PHP. This is the very easy method to get the Facebook page detail. So Let’s see how to get this done. With this method you can get details of any Facebook page [inluding] name, picture, link, website, products, description and if the user can post to it.
The sample code is only a few lines - it uses the Facebook page ID (easy to grab from the URL) and fetches a URL with it as a parameter. The output is returned as a standard PHP object with all of the properties attached (decoded from JSON). This is just one of many methods the Facebook graph API has, so check out their documentation for more methods and details on returned values.
