I am trying to access information such as name and logo in the Infobox company section returned when a search is performed using the code below. I've used an example of google. If the exit command is removed it can be seen that I can access contentformat and contentmodel in the [0] object however I am struggling to access anything in the [*] array within this object. Forgive the silly question, as I'm sure I'm missing something but any assistance is most appreciated.

<h2>Search</h2>
<form method="post">
Search: <input type="text" name="q" value="google" />
<input type="submit" value="Submit">

<?php
if (isset($_POST['q'])) {
$search = $_POST['q'];
$url_2 = "http://en.wikipedia.org/w/api.php?
action=query&prop=revisions&rvprop=content&format=json&titles=$search&rvsection=0&continue=";
$res_2 = file_get_contents($url_2);
$data_2 = json_decode($res_2);
echo "<pre>";
print_r($data_2);
echo "</pre>";
exit;
?>
<h2>Search results for '<?php echo $search; ?>'</h2>
<ol>
<?php foreach ($data_2->query->pages as $r):
?>
<li>
<?php echo $r->revisions[0]->contentformat; ?>
</li>
<?php endforeach; ?>

Solution: don't use Wikipedia as a database, instead use Wikidata.org which is its own database.
Docs: http://www.wikidata.org/w/api.php?action=help&modules=wbgetclaims

If you need to find the entity ID and you know the article name in one Wikipedia language, pywikibot can help: it will be something like
and you can continue from there.
