php怎么实现多次回复?
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'
