This article mainly introduces the implementation case of PHP registration and login interface. Interested friends can refer to it. I hope it will be helpful to everyone.

At first I thought the two functions of registration and login on a website were magical. Later, I did some research and found that the truth is actually very simple. Let’s take a look at how to implement it. . . .

I created several files on my computer:

success.html (Login success redirect page)

return.html (Registration success page )

, everything is just some html tags as follows:




登录界面





账号：



密码：


没有账号，注册

Copy after login




会员注册





账  户：



密  码：



密码确认：

Copy after login

return.html is the page that appears after successful registration. There is a js code in it that is used to return to the login interface regularly




无标题文档




注册成功！

5秒后返回登录界面

你也可以直接点击回到登录页面

Copy after login

"."window.alert"."("."\""."请填写完成！"."\"".")".";"."";
          echo"";    
          exit;
        }
        if($password1==$password2)//确认密码是否正确
        {
        $str="select count(*) from register where username="."'"."$name"."'";
        $result=mysql_query($str,$link);
        $pass=mysql_fetch_row($result);
        $pa=$pass[0];
        if($pa==1)//判断数据库表中是否已存在该用户名
        {
        
        echo"";
        echo"";   
        exit; 
        }
        
        
        $sql="insert into register values("."\""."$name"."\"".","."\""."$password1"."\"".")";//将注册信息插入数据库表中
        //echo"$sql";
        mysql_query($sql,$link);
        mysql_query('SET NAMES UTF8');
        $close=mysql_close($link);
        if($close)
        {
          //echo"数据库关闭";
          //echo"注册成功！";
          echo"";    
        }
        }
        else
        {
          echo"";
          echo"";    
        }
      }
    }
  }
?>

Copy after login

"."window.alert"."("."\""."请填写正确的信息！"."\"".")".";"."";
        echo"";
        exit;
      }
      $str="select password from register where username="."'"."$name"."'";
      mysql_query('SET NAMES UTF8');20       $result=mysql_query($str,$link);
      $pass=mysql_fetch_row($result);
      $pa=$pass[0];
      if($pa==$password)//判断密码与注册时密码是否一致
      {
        echo"登录成功！";
        echo"";
      }
      {  
        echo"";
        echo"";
      }
    }
    
  }
}
?>
