本文实例为大家分享了php匿名聊天室的具体实现代码，供大家参考，具体内容如下

1. index.html

2. action.php

$link = mysqli_connect('localhost', 'root', '123', 'test');

mysqli_query($link, 'set names utf8');

$info= array();

header("Content-type: text/html; charset=utf-8");

$id=$_GET['maxid'];

$data = mysqli_query($link, "select * from talk where id>$id");

while ($array = mysqli_fetch_assoc($data)) {

$info[] = $array;

};

echo json_encode($info);

3. chat.sql

DROP TABLE IF EXISTS `talk`;

CREATE TABLE `talk` (

`id` int(10) unsigned NOT NULL AUTO_INCREMENT COMMENT 'id',

`send` varchar(10) CHARACTER SET utf8 DEFAULT NULL COMMENT '发送者昵称',

`ip` varchar(12) CHARACTER SET utf8 DEFAULT NULL,

$time= date("Y-m-d H:i:s", time(0));

$link = mysqli_connect('localhost', 'root', '123', 'test');

mysqli_query($link, 'set names utf8');

$ip = $_SERVER["REMOTE_ADDR"];

$sql="INSERT INTO talk VALUES(NULL,'匿名者','$ip','$content','$time')";

$data = mysqli_query($link,$sql);

echo "$content";
