Combine site content with external site rss

[asanti]

I'm currently running a classified ads site and planning to display my own content from database combined with and external site rss. So here is what i got right now after the db query for the jobs ads (procedural php),

while ($row = mysqli_fetch_array($results, MYSQLI_ASSOC)){



echo '<div class="media margin-none">

<a class="pull-left bg-inverse innerAll text-center" href="#"><img src="'.$foto.'" share_alt="" width="100" height="100"></a>

<div class="media-body innerAll">

<h4 class="media-heading innerT">

<a href="' . $row['title'] .'-da' . $row['id_ad'] . '" class="text-inverse">'. $remuneracion .'   ' . substr(ucfirst(strtolower($row['title'])), 0, 53) . '</a> <small class="pull-right label label-default"><i class="fa fa-fw fa-calendar-o"></i> ' . $row['date_created'] . '</small></h4>

<p>' . substr(ucfirst(strtolower($row['description'])), 0, 80) . ' ...</p>';


echo '</div>

</div>

<div class="col-separator-h"></div>';

}


echo pagination($statement,$per_page,$page, $url_filtros, $filtros);

?>

it is the while loop that i use to display ads from my database, what could be the best way to display (in this same loop?) other site's rss feed so i can show my content combined with the external rss?

Thanks
