What does this code do?
<pre><code>&lt;a href="http://www.google.com/search?q='.urlencode(current(explode('(', $ask_key))).'" target="_blank"&gt;
</code></pre>

<p>I can't understand what <code>urlencode(current(explode('(', $ask_key )))</code> does.<br>
Can anybody explain me what that code does?</p>
