+
+1. ### **link数据库(后面都要用上)**
+
+```php
+<?php
+$link=mysqli_connect("127.0.0.1","root","wjj1929707670","user");
+mysqli_query($link,"set names utf8");//注意防乱码的设置
+```
+
+
+
+2. ### **注册**
+
+```php
+<?php
+session_start();//和数据库一样，每次用session时都要启动哦！
+$user_name=$_POST['user_name'];
+$password=$_POST['password'];
+$password2=$_POST['password2'];
+$phone=$_POST['phone'];//分别用变量把用户提交的数据封装
+
+
+//空信息不能注册，所以首先判断不能为空
+if(!empty($user_name)&& !empty($password) && !empty($password2)&&!empty($phone)){
+//满足信息不为空后进一步判断两次输入的密码是否正确
+    if ($password==$password2){
+        include_once ("Link.php");
+        $sql="insert into `user` values (null,'$user_name',$password,$phone)";
+//以上条件都满足则把用户要注册的信息存到数据库
+     $result= mysqli_query($link,$sql);
+        if ($result){
+            header('location:'.'login.php');
+// header()自动跳转，<a>——手动跳转
+           // echo "<a href='login.php'>注册成功，请登录！</a>";
+        }else{
+            echo  "注册失败";
+        }
+

+//和注册一样先判断不为空
+ if (!empty($user_name)&&!empty($password)){

+    $sql="select * from `user` where `user_name`='$user_name' and `password`=$password";
+   $result= mysqli_query($link,$sql);
+  //   select 返回的是结果集，不能直接判断,应该判断结果集的行数，所以这里不能if($result)，还有注意SQL语句里的$name是不i是‘$name’，加引号
+     
+     
+  $num= mysqli_num_rows($result);//mysqli_affected_rows:取得前一次MYSQL操作所影响的记录行数，操作数是指INSERT、UPDATA、DELETE、影响的是指修改、变化的。
+   //  mysqli_num_rows()返回结果集中行的数目、仅对SELECT语句有效。
+
+     if ($num>0){
+         $_SESSION['user_name']=$user_name;// 相当于是成功后有个标识
+         header('location:' . 'homepage.php');
+     }else{

+     }
+ }
+?>
