本文使用原生PHP和mysql数据库，使用jquery的ajax实现注册功能。

创建数据库sql
创建数据库
CREATE DATABASE db100;
创建数据表
DROP TABLE IF EXISTS `user`;
CREATE TABLE `user` (
`id` int(11) unsigned NOT NULL AUTO_INCREMENT,
`username` varchar(20) NOT NULL,
`password` varchar(255) NOT NULL,
`email` varchar(255) DEFAULT NULL,
`regtime` int(11) DEFAULT NULL,
PRIMARY KEY (`id`)
) ENGINE=InnoDB AUTO_INCREMENT=6 DEFAULT CHARSET=utf8;
数据库连接文件
<?php
// 连接数据库
$servername = "localhost";
$username = "root";
$password = "root";
$dbname = "db100";
$conn = new mysqli($servername, $username, $password, $dbname);
if ($conn->connect_error) {
die("Connection failed: " . $conn->connect_error);
}
?>
注册PHP文件
<?php
include 'conn.php';
// 获取前端传来的数据
$username = $_POST['username'];
// $password = password_hash($_POST['password'], PASSWORD_DEFAULT); // 对密码进行哈希加密
$password = $_POST['password'];
$email = $_POST['email'];
// 验证输入并尝试插入数据
$sql = "INSERT INTO user (username, password, email)
VALUES (?, ?, ?)";
$stmt = $conn->prepare($sql);
$stmt->bind_param("sss", $username, $password, $email);
if ($stmt->execute()) {
echo json_encode(array('status' => 'success'));
} else {
echo json_encode(array('status' => 'error', 'message' => '注册失败，请检查您的输入或稍后再试.'));
}
$stmt->close();
$conn->close();
?>
