Generate raw Facebook total share/like count in PHP

I have a theme file named profiles.tpl.php that styles a page like this: http://www.pointsincase.com/user/6320

On the list of new columns for the user, I want to dynamically generate the raw number of Facebook total share/like counts next to the date. For instance "Feb 22, 2013 | 24 Likes on Facebook".

This is how the code currently looks:

$columns .=  '<div class="clear"></div><div class="profarticle">' . $img . '<font size="3">' . l($node->title, 'node/' . $node->nid) . '</font><div style="line-height:65%;"><br></div><font style="font-size:85%">' . $node->content . '</font><br/><font style="font-size:80%" color="#757575"><em>' . 
                        '' . format_date($node->created, 'custom', 'M j, Y') . '</em></font><br /></div><hr size="1" color="#D0D0D0" style="margin-top: 10px; margin-bottom: 10px;">';

Can anyone help me insert the correct code in there to output the Facebook total share/like count?

I am aware of the following code available from Facebook available for such a request:

$facebook->api_client->fql_query('SELECT total_count FROM link_stat WHERE url="YOUR_SHARE_URL"');

...but I don't know if more code is needed to define "$facebook", or what code to replace "YOUR_SHARE_URL" to generate each full node URL.
