php - 尝试在xampp中连接sql数据库

Question

<?php

$host = 'localhost';
$user = 'root'
$password = '';
$db ='members';

$connection = mysqli_connect("localhost", "user", "password") or die("Unable to connect to the server!");

mysqli_select_db("members", $connection) or die("Couldn't connect to the database!");

我已经安装了 xampp 并创建了名为“members”的数据库。我尝试将其连接到 phpmyadmin 但没有成功。三天以来我尝试用谷歌搜索所有答案，但徒劳无功。请帮助我...

<?php
$host = 'localhost';
$user = 'root';
$password = '';
$db ='members';

$connection = mysqli_connect($host,$user,$password,$db);// you can select db separately as you did already
if($connection){
     // do all your stuff that you want
}else{
   echo "db connection error because of".mysqli_connect_error();
}
