getaddrinfo失败：没有这样的主机

Question

I tried to connect to phpMyAdmin database but encounter an error Warning: mysqli::mysqli(): php_network_getaddresses: getaddrinfo failed: No such host is known. Below coding is the one that I currently use.

$servername = "http://localhost:8080";
$username = "root";
$password = "";
$db = "dbLogin";

$conn = new mysqli($servername, $username, $password, $db);

if ($conn->connect_error) {
    die("Connection failed: ".$conn->connect_error);
}
else {
    echo "Connection success!";
}

When I run my system, It will still show the message connection success! but together with the error I mentioned.

Answer 1

replace server name from

$servername = "http://localhost:8080";

to

$servername = "localhost";
