Get Facebook “Like” count for every page on my domain

Actually I would do it this way:

$arrayOfPages = array('url1', 'url2', 'url3');

$listOfPages = implode(',', $arrayOfPages);

SELECT share_count, like_count, comment_count, total_count, url
FROM link_stat
WHERE url IN ($listOfPages)

That would give you all the data with the URL as a unique identifier without having to break Facebook’s policy against fake users. You can dynamically create the $arrayOfPages variable from a query on your site’s database.
