如何使用php连接MySQL db（xampp）？

Question

我正在尝试连接到phpstorm中的mysql数据库，但我没有成功。 我将非常感谢你的帮助。

<?php
$servername = "http://localhost:8012";
$username = "root";
$password = "";

// Create connection
$conn = new mysqli($servername, $username, $password);

// Check connection
if ($conn->connect_error) {
    die("Connection failed: " . $conn->connect_error);
}else{
die("Connected successfully");
}

错误是：502 Bad Gateway
