给大家分享一个简单的PHP实现注册教程:

<?php

/*
 * 建表SQL语句
 *
 *create table emp_user(
    id int unsigned auto_increment primary key,
    user_name varchar(10) not null unique,
    password char(32) not null,
    email varchar(40) not null
)charset=utf8;
 *
 *
 *
 */


?>

<html>
<head>
    <title>用户注册</title>
    <script type="text/javascript">
        function checkInput(form) {
            var user_name;
            user_name = form.user_name;
            if(user_name.value == '')
            {
                alert('不能为空！');
                return false;
            }

            var email = document.getElementById('email');
            if(email.value == '')
            {
                alert('能为空！');
                return false;
            }

            if(document.forms[0].password.value == '')
            {
                alert('能为空');
                return false;
            }

            var pwd = form.password;
            var pwd_2 = document.getElementById('password_2');
            if(pwd.value != pwd_2.value)
            {
                alert('不一致！');
                return false;
            }
            return true;
        }
    </script>
</head>
<body>
<form name="form1" method="post" action="./t206.php" onsubmit="return checkInput(this);">
    <h2></h2>
    <p>：<input type="text" name="user_name" id="user_name"></p>
    <p>：<input type="text" name="email" id="email"></p>
    <p>：<input type="password" name="password" id="password"></p>
    <p>：<input type="password" name="password_2" id="password_2"></p>
    <p><input type="submit" name="register" id="register" value="注册" style="width: 150px;"></p>
    <p><input type="reset" value="重新填写" style="width: 150px;"></p>
</form>
</body>
</html>

<?php
header('Content-type:text/html;charset=utf-8');
//判断点击按钮
if(isset($_POST['register']))
{
    echo "<hr>";
    $user_name = $_POST['user_name'];
    $email = $_POST['email'];
    $password = $_POST['password'];
    //连接数据库
    $connect = mysqli_connect('localhost','root','mysql123','test');
    if(!$connect)


?>
