我是非常新的PHP所以请原谅我的新代码,虽然我需要使用PHP,但是我更需要使用PHP,目前我有php页面连接到数据库,如果成功将值存储到cookie中虽然由于字符串不正确而抛出这些错误消息

Warning: Illegal string offset 'Member_Username' in C:\xampp\htdocs\awm\includes\login.php on line 10

Warning: Illegal string offset 'Member_Password' in C:\xampp\htdocs\awm\includes\login.php on line 10

Notice: Trying to get property of non-object in C:\xampp\htdocs\awm\includes\login.php on line 13

这是我的代码:

<?php

try
{
    $Username = $_POST['Username'];
    $Password = $_POST['Password'];

    $con = mysqli_connect('localhost','root','Password','Letting');

    $query = "SELECT Member_Id, Member_Firstname, Member_Surname FROM Members WHERE Member_Username = '" . $Username['Member_Username'] .  "' AND Password = '" . $Password['Member_Password']. "'";
    $result = $con->query($query);

    if($result->num_rows)
    {
        $row = $result->fetch_assoc();

        $_SESSION['MemberId']=$row['Member_Id'];
        $_SESSION['Firstname']=$row['Member_Firstname'];
        $_SESSION['Surname']=$row['Member_Surname']; …
