Sort in a multi dimentional array
<p>I have this array in PHP:</p>

<pre><code>foreach($rss_items as $item) :
    $contenu[] = array (
        "auteur" =&gt; $author,
        "date" =&gt; $item-&gt;get_date(),
        "contenu" =&gt; $item-&gt;get_content()
    );
</code></pre>

<p>At the end, my array is composed of 6 parts, which everyone contains the 3 variable above.
My question is: How can I sort the array by date and using the strtotime because it's easier to sort with this function.</p>

<pre><code>strtotime($item-&gt;get_date());
</code></pre>
