}
$name = $_POST['name'];
$pwd = md5($_POST['pwd']);
$sql = "insert into 表 (username,password) values ('$name','$pwd')";
$exec = $pdo-query($sql);

$sql = "select user_id from 表名 where username='$name' and password='$pwd'";
$stmt = $pdo-query($sql);
$info = $stmt-fetch(PDO::FETCH_ASSOC);
if($info){
echo "登录成功";
}else{
echo "登录失败";
}
}
大概这样

求一个简单的PHP注册，登陆代码
我帮你找了个小程序
程序介绍：
1、共4个页面，conn.php连接数据库、img.php图片验证码、index.php登录页面、register.php注册页面
2、注册页面全是用js来验证的，所以不太完善，后续会改进
3、还没有学习ajax，所以图片没法点击刷新。原谅我吧
4、每段代码都含有详细注释，方便交流学习
程序使用：
1、下载源码上传到你网站某个目录
2、打开你的数据库，在某个表中执行readme.txt中的SQL语句创建字段用来存放用户数据
3、修改conn.php填写对应的数据库地址、用户名、密码、数据表
4、确保上述操作无误后，打卡URL地址进行测试
源码git地址
php注册功能代码
注册页面表单提交时没有提交sex字段，$_SESSION['sname']没有赋值，可以直接在前面加上error_reporting(E_ALL^E_NOTICE)，防止NOTICE报出
