<?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, `content` varchar(500) CHARACTER SET utf8 DEFAULT NULL, `time` varchar(50) DEFAULT NULL, PRIMARY KEY (`id`) ) ENGINE=InnoDB AUTO_INCREMENT=52 DEFAULT CHARSET=utf8;
4. add.php
<?php /** * @功能 将表单插入数据库 */ $content=$_POST[content]; print_r($_POST); $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 $content; if($data) echo 1; else echo 0;
