PHP SP2版，查看自己发表的留言的回复

我想在前台做个页面，专门让人查看自己的留言，如管理员回复了，也可在该页面查看

                         {king:feedback}
                            <div class="forumtitle"><strong>{king:title/}</strong></div>
                         <div class="forumlist">
        <div class="usercontainer">
                                 <span class="useravatar">#{king:id/} {king:username/}</span><em>{king:DATE formatdate="Y-m-d H:i:s"/}</em>
                                </div>
                                <div class="formesg">
                                 <div class="contentmesg">{king:content/}</div>
                                    <?php if('{king:isreply/}'){
          echo '<div class="reply"><h4>管理员回复:</h4>'.{king:reply/}.'</div>';
            }?>                                 
                                </div>
                            </div>
                            {/king:feedback}

我不知道这里怎么做判断，把自己的留言显示出来。。。。
