创建数据表：demo
-- -- 表的结构 `demo` -- CREATE TABLE IF NOT EXISTS `demo` ( `id` int(11) NOT NULL AUTO_INCREMENT, `name` varchar(20) COLLATE utf8_bin NOT NULL, PRIMARY KEY (`id`) ) ENGINE=InnoDB DEFAULT CHARSET=utf8 COLLATE=utf8_bin AUTO_INCREMENT=5 ; -- -- 转存表中的数据 `demo` -- INSERT INTO `demo` (`id`, `name`) VALUES (1, '雷军'), (2, '马化腾'), (3, '李彦宏'), (4, '马云');
服务器文件：demo.php
<?php $mysqli = new mysqli("localhost","root","","test"); $mysqli->set_charset('utf8'); $query = 'SELECT * FROM demo'; $result = $mysqli->query($query); $arr = $result->fetch_all(MYSQLI_ASSOC); $info = json_encode($arr); echo $json = '{"success":true,"info":'.$info.'}';
