    <p>I am trying to get information on the likes of the page, since I want to order the posts of my site by likes. I decided to do it by scraping the page, and store the likes of each post id in db, then I can just order using the db. (I can run this 'scraper' every hour or something like that to update the results)</p> <p>I am doing the following: </p> <pre><code> $url = "http://www.mydomain.com"; $html = file_get_contents($url); $dom= new domDocument; $dom-&gt;loadHTML($html); </code></pre> <p>And I am getting the following errors:</p> <pre><code>Notice: DOMDocument::loadHTML() [domdocument.loadhtml]: Namespace prefix fb is not defined in Entity, line: 36 in C:\xampp\htdocs\page.php on line 13 Warning: DOMDocument::loadHTML() [domdocument.loadhtml]: Tag fb:like invalid in Entity, line: 36 in C:\xampp\htdocs\page.php on line 13 </code></pre> <p>Somehow the likes are not shown? Also if I do something like this:</p> <pre><code> $url = "http://www.mydomain.com"; $html = file_get_contents($url); echo $html; preg_match_all( '/&lt;div id="LikePluginPagelet".*?&gt;.*?&lt;\/div&gt;/s', $html, $posts, PREG_SET_ORDER ); print_r($posts) </code></pre> <p>The first 'echo' actually shows the whole page, but then the print_r just shows <code>Array ( )</code> </p> <p>Is it possible that some things cannot be grabbed via php? Here is an example page: <a href="http://developers.facebook.com/docs/reference/plugins/like/" rel="nofollow">http://developers.facebook.com/docs/reference/plugins/like/</a></p> <p>You can see that where the like is and the number of likes, the div has id 'LikePluginPagelet', but PHP does not obtain the stuff inside it.</p> <p>Update:</p> <p>Can you make code that will get the 500K number of likes from here by scraping the page? <a href="http://developers.facebook.com/docs/reference/plugins/like/" rel="nofollow">http://developers.facebook.com/docs/reference/plugins/like/</a> Or any other page that contains a number of likes, if I can get that I can use it in my code as well.</p> <p>Thanks!</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
