Wikipedia search api with much side information - php

Question

I want to take some information about my query from wikipedia using php. I want to have a description, title, img url (if exists), and some side information about it. For example like the google wikipedia information, with much side information.
Until now i have only the description & title.
My code:
$q = str_replace("#", "", ucwords($query));
$opts = array('http' =>
array(
'user_agent' => 'Mozilla Firefox www (http://www.mozilla.org)'
)
);
$context = stream_context_create($opts);
$url = 'en.wikipedia.org/w/api.php?action=opensearch&search='.$q.'&limit=1&namespace=0&format=xml';
#$wiki_arr = simplexml_load_file($url);
if(#$wiki_arr->Section->Item->Text == "" or #strtolower($wiki_arr->Section->Item->Text) != strtolower($q))
{
return "";
}
$title = $wiki_arr->Section->Item->Text;
$description = $wiki_arr->Section->Item->Description;
$url = $wiki_arr->Section->Item->Url;
$result = "".$title.", ".$description.", ".$url."";

Answer 1

Once again, there is no such thing as a Wikipedia API. There is a MediaWiki web API. If something doesn't exist there, it doesn't exist at all in wikipedia.org.
For your question: you said you want to do something like the Wikipedia card in the Google Knowledge Graph. What powers that? Freebase. What's the Wikimedia projects equivalent of Freebase? Wikidata.org. (And not only for Wikipedia, but also for Wikisource etc.) So, please use the Wikidata data, via its API which is documented by itself: http://wikidata.org/w/api.php
You can check the [[wikidata:list of properties]] to know what kind of data to access, and [[mediawikiwiki:Category:Wikibase]] for other libraries to access the API. An example of what you can do this way is wdsearch.js, another reasonator at tools.wmflabs.org (sorry, can't add more links).
