Sort Results

[eluser]Unknown[/eluser]
Hello,
I'm trying to sort a group of listings. Each listing is in subcategory. How can I print the subcategory name, one time, followed by all the listings in the subcategory.

Thanks in advance

Code:

<?foreach($results as $result) {?>
<p>
&lt;?=$result->subcategory_subcategory;?&gt;<br />
&lt;?=$result->item_title;?&gt;<br />
&lt;?=$result->item_description;?&gt;<br />
</p>
&lt;?}?&gt;
