Invalid parse_str input
<p>Is there any input that can be passed to <a href="http://php.net/manual/en/function.parse-str.php" rel="nofollow">parse_str</a> that will result in the second reference parameter <strong>not</strong> being set to an array?</p>

<p>So, a value <strong>$x</strong> that will cause the conditional to be true.</p>

<pre><code>parse_str($x, $array);
if (is_array($array) === false)) {
    echo $x . ' wont parse to an array!';
}
</code></pre>

<p>I tried, <code>null</code>, <code>false</code> and a couple of strings, and all of them cause <code>$array</code> to be an empty array.</p>
