how to check if the second array key is an array?
<p>i have an array which could look like this:</p>

<pre><code> $config[$name][$array]['key'] = 'value'; // here it's an array
</code></pre>

<p>or</p>

<pre><code> $config[$name][$array] = 'value'; // here it's not an array
</code></pre>

<p>i want to check if the second array key ('array') is an array or not.</p>

<p>could someone help me?</p>
