comment_content kelime yada harf sınırlaması nasıl yapılır ?

son yorumları yorum yapan avatarı, yorum yapan ismi, konu başlığı ve yorum olarak listeleyen bir kod buldum tek sorun yapılan yorumun tamamen çıkması anladığım kadarı ile yorum içeriği "comment_content" kodundan geliyor bir sınırlama getiremiyorum

          <?php
            // Recent comments
            $max = 10; // item to get
            global $wpdb;
            $sql = "SELECT c.*, p.post_title FROM $wpdb->comments c INNER JOIN $wpdb->posts p ON (c.comment_post_id=p.ID) WHERE comment_approved = '1' AND comment_type not in ('trackback','pingback')";
            $sql .= " ORDER BY comment_date DESC LIMIT $max";
            $results = $wpdb->get_results($sql);
            
            $template = '<div class="who">%g <a href="%au">%an</a> on <a href="%pu#comment-%cid">%pt</a></div>';
            
            $echoed=0;
            foreach ($results as $row) {
              $tags = array('%ct','%cd','%g','%pt','%pu','%au','%an','%cid');
              $replacements = array($row->comment_title,$row->comment_date,get_avatar($row->comment_author_email,'32'),$row->post_title,get_permalink($row->comment_post_ID),$row->comment_author_url,$row->comment_author,$row->comment_ID);
              echo '<li>' . str_replace($tags,$replacements,$template) . '<div class="said">'. $row->comment_content . '</div></li>';
              $echoed=1;
            }
            if ($echoed==0)
                echo '<li>None Found.</li>';        
          ?>
          </ul>

<div class="said">'. $row->comment_content . '</div> kodu yerine;

<div class="said">'. $row->comment_excerpt . '</div> denedim olmadı yorum tamamen kayboldu

              echo '<li>' . str_replace($tags,$replacements,$template) . '<div class="said">'.comment_excerpt($row->comment_ID). '</div></li>';
              $echoed=1;
            }
            if ($echoed==0)
                echo '<li>None Found.</li>';        
          ?>
          </ul>

Bunu dener misin? Excerpt uzunluğunuda kendine göre ayarlaman gerekiyor.

teşekkürler kod çalıştı ama anlayamadığım excerpt uzunluğu naıl ayarlanıyor kısıtlama için bir rakam göremedim

9 karakter olarak ayarladım. 9 rakamını kendine göre değiştirebilirsin.

teşekkürler @rugzO hocam
