如何连接到mysql数据库[关闭]

Question

How do I connect to a MySQL database in PHP?

• Database name: NewDB1
• Username : Mark
• Password : secret

I have googled a few solutions, but none of them seem to work.

Answer 1

<?php
$servername = "localhost";
$username = "Mark";
$password = "secret";

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

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