php - Is a query-inside-query to display categories like this possible? -

function getforums($id) {     $currenthost = "http://$_server[http_host]";     $query = "select * categories";     try {         global $db;         $stmt = $db->prepare($query);          $stmt->execute();         $result = $stmt->fetchall();         foreach($result $row) {             $category_title = $row['category_title'];             $category_id = $row['category_id'];             echo '<div class="forum pleft">                     <div class="forum-header">                         <span class="header-text">'.$category_title.'</span>                     </div>                     <table>';             $query2 = "select * forums category_id='".$category_id."'";             try {                 global $db;                 $stmt2 = $db->prepare($query2);                  $stmt2->execute();                 $result2 = $stmt2->fetchall();                 foreach($result2 $row2) {                     $forum_cat_id = $row2['category_id'];                     $forum_id = $row2['forum_id'];                     $forum_title = $row2['forum_title'];                     $forum_topic_count = $row2['forum_topic_count'];                     $forum_post_count = $row2['forum_post_count'];                     $forum_last_topic_id = $row2['forum_last_topic_id'];                     $forum_last_topic = $row2['forum_last_topic'];                     $forum_last_date = $row2['forum_last_date'];                     $forum_last_user = $row2['forum_last_user'];                     $fixed_last_topic = substr($forum_last_topic,0,25).'...';                     echo '<tr>                             <td class="title"><a href="'.$currenthost.'/forums/view-forum/index.php?cid='.$forum_cat_id.'&fid='.$forum_id.'">'.$forum_title.'</a></td>                             <td class="topics">'.$forum_topic_count.'</td>                             <td class="posts">'.$forum_post_count.'</td>                             <td class="lastpost"><a href="'.$currenthost.'/forums/view-thread/index.php?cid='.$id.'&fid='.$forum_id.'&tid='.forum_last_topic_id.'">'.$fixed_last_topic.'</a> <a href="'.$currenthost.'/users/index.php?username='.$forum_last_user.'">'.$forum_last_user.'</a> @ '.$forum_last_date.'</td>                         </tr>                     </table>                 </div>';                 }             }         } // getting error here!     }     catch(pdoexception $ex) {         die("error");     } }
