Array only values in keys numeric order
<p>I've an array like this:</p>

<pre><code>8:16, 9:8, 10:11, 11:5, 12:5, 13:13, 14:42
</code></pre>

<p>and I want it to be:</p>

<pre><code>0:16, 1:8, 2:11 ....
</code></pre>

<p>in PHP.</p>

<p>I know I can do an own function. but I think it should be one built in.</p>

<p>I've tried: array_values</p>
