This article mainly introduces the PHP Mysql implementation of imitating NetEase comments and building a building. It has a certain reference value. Now I share it with you. Friends in need can refer to it.

You may have read NetEase comments. That kind of building-like citation, this article uses php and mysql to achieve this effect.

First design a data table to store the comment data: 

DROP TABLE IF EXISTS `comment`;
CREATE TABLE `comment` (
  `id` int(10) unsigned NOT NULL AUTO_INCREMENT,
  `username` varchar(32) NOT NULL,
  `site` varchar(128) DEFAULT NULL,
  `content` varchar(1000) NOT NULL,
  `time` datetime NOT NULL,
  `pid` int(10) NOT NULL,
  `articleid` int(10) NOT NULL,
  PRIMARY KEY (`id`)
) ENGINE=InnoDB AUTO_INCREMENT=8 DEFAULT CHARSET=utf8;

The key field is pid, which saves the id of the referenced comment. If there is no reference, set it to 0.

The specific implementation mainly uses a recursive algorithm to find all referenced comments (similar to the unlimited classification menu). The code is as follows: 

<?php 
    require_once"sqlHelper.class.php";
     
    //连接数据库
    $sqlHelper= new SqlHelper(&#39;localhost&#39;,&#39;root&#39;, &#39;root&#39;,&#39;test&#39;, 3306);
 
    //插入评论数据
    if(isset($_POST) && !empty($_POST)){
        $comment= array();
        $comment[&#39;username&#39;] =$_POST[&#39;name&#39;]?$_POST[&#39;name&#39;]:&#39;匿名&#39;;
        $comment[&#39;site&#39;] =$_POST[&#39;site&#39;]?$_POST[&#39;site&#39;]:&#39;
 &#39;; 
        $comment[&#39;pid&#39;] =$_POST[&#39;commentid&#39;]?$_POST[&#39;commentid&#39;]:&#39;0&#39;;
        if($comment[&#39;pid&#39;]
 == $comment[&#39;id&#39;]){
            $comment[&#39;pid&#39;] =&#39;0&#39;;
        }
        $comment[&#39;content&#39;] =$_POST[&#39;content&#39;]?$_POST[&#39;content&#39;]:&#39;...&#39;;
        $comment[&#39;articleid&#39;] =$_POST[&#39;articleid&#39;]?$_POST[&#39;articleid&#39;]:&#39;1&#39;;
        $comment[&#39;time&#39;] = date ( &#39;Y-m-d H:i:s&#39;, time () );
 
        $sql_str= $sqlHelper->get_replace_db_sql("comment",$comment);
        //echo $sql_str;
        $sqlHelper->insert_db($sql_str);
    }
?>
