Google Image search in Php
<p>I'm trying to use google images api with PHP, and I'm really not sure what to do.</p>

<p>I have written the following Code</p>

<pre><code>&lt;?php
$url = "https://ajax.googleapis.com/ajax/services/search/images?".
"v=1.0&amp;q=indian%20institue%20of%20techology";
$jk=file_get_contents($url);
$json = json_decode($jk, true);
echo $json["responseData"]["results"][0]["url"];
?&gt;
</code></pre>

<p>I wish to find the url of 1st Image from image search.
I'm not getting any result when using the script.</p>
