thinkPHP框架实现的无限回复评论功能示例

function CommentList($pid = 0, &$commentList = array(), $spac = 0) {
    static $i = 0;
    $spac = $spac + 1; //初始为1级评论
    $List = M('comment')->
        field('id,add_time,author,content,pid')->
        where(array('pid' => $pid))->order("id DESC")->select();
    foreach ($List as $k => $v) {
      $commentList[$i]['level'] = $spac; //评论层级
      $commentList[$i]['author'] = $v['author'];
      $commentList[$i]['id'] = $v['id'];
      $commentList[$i]['pid'] = $v['pid']; //此条评论的父id
      $commentList[$i]['content'] = $v['content'];
      $commentList[$i]['time'] = $v['add_time'];
      // $commentList[$i]['pauthor']=$pautor;
      $i++;
      $this->CommentList($v['id'], $commentList, $spac);
    }
    return $commentList;
}
