Get primary category if more than one is selected? : <p>In Wordpress, how can I revert to the primary category?</p>

<p>I'm using the following loop, if all three are checked then it just reverts to the last term. I want to make sure it's the primary category.</p>

<pre><code>&lt;?php $term_list = wp_get_post_terms($post-&gt;ID, 'category', array("fields" =&gt; "names"));
foreach ($term_list as $term) {
    $name = $term;
} ?&gt;
</code></pre>
