PHP无限级评论回复功能实现

protected  function commentList($aid,$pid = 0,&$result=array()){
    $arr = ArticleComment::relation(['usertalent'=> function($query){
        $query->field('id,talent_usernickname,talent_avatar');
    }])->where(['pid' => $pid])->where(['article_id' => $aid])->order('id desc')->select();
    if(empty($arr)){
        return array();
    }
    foreach ($arr as $cm) {
        $thisArr=&$result[];
        $cm["children"] = $this->commentList($aid,$cm["id"],$thisArr);
        $thisArr = $cm;
    }
    return $result;
}

调用方法
$this->commentList($aid);

项目中使用tp5写文章评论回复功能
表中使用pid来标识回复表的id 表结构如下

CREATE TABLE `bcpub_article_comment` (
`id` int(11) unsigned NOT NULL AUTO_INCREMENT,
`author_id` int(11) unsigned NOT NULL DEFAULT '0' COMMENT '作者ID',
`article_id` int(11) unsigned NOT NULL DEFAULT '0' COMMENT '文章ID',
`pid` int(11) unsigned NOT NULL DEFAULT '0',
`uid` int(11) unsigned NOT NULL DEFAULT '0' COMMENT '评论人ID',
`comment` varchar(250) NOT NULL DEFAULT '',
`give_count` int(10) unsigned NOT NULL DEFAULT '0' COMMENT '评论点赞数量',
`add_time` int(10) unsigned NOT NULL DEFAULT '0',
PRIMARY KEY (`id`),
KEY `author_id` (`author_id`),
KEY `pid` (`pid`)
) ENGINE=MyISAM AUTO_INCREMENT=97 DEFAULT CHARSET=utf8 COMMENT='文章评论表'
