in_array doesn't make any sense
<pre><code>$arr = array(
    'test' =&gt; array(
        'soap' =&gt; true,
    ),
);

$input = 'hey';
if (in_array($input, $arr['test'])) {
    echo $input . ' is apparently in the array?'; 
}
</code></pre>

<p>Result:
 hey is apparently in the array?</p>

<p>It doesn't make any sense to me, please explain why. And how do I fix this?</p>
