Add class to first row PHP
<p>I have a loop pulling information from my database. How can I add a class to my first row without using jQuery? </p>

<pre><code>while ( $query-&gt;have_posts() ) : $query-&gt;the_post();
                    if ( $keys = get_post_custom_keys() ) {
                      echo "&lt;div class='card-prod'&gt;&lt;span class='card-title'&gt;";
                      echo the_title();
                      echo "&lt;/span&gt;";

                      foreach ( (array) $keys as $key ) {
                        $keyt = trim($key);
                        if ( '_' == $keyt{0} || 'pricing' == $keyt || 'vehicleType' == $keyt || 'coverageRegion' == $keyt || 'locationType' == $keyt )
                          continue;
                        $values = array_map('trim', get_post_custom_values($key));
                        $value = implode($values,', ');
                        echo "&lt;span class='srch-val'&gt;".apply_filters(" $value\n", $value)."&lt;/span&gt;";
                      }
                      echo "\n";
                      echo '&lt;img src="wp-content/themes/cafc/images/cards/dummy.png" /&gt;';
                      echo the_excerpt()."&lt;/div&gt;";}
                endwhile;
</code></pre>
