What steps can be taken to troubleshoot and fix a missing connection to a MySQL database in PHP?

If you are experiencing a missing connection to a MySQL database in PHP, you can troubleshoot and fix this issue by checking the database credentials, ensuring the MySQL server is running, and verifying the database permissions. Additionally, you can use error handling to catch any connection errors and provide more detailed information on the problem. 

<?php
$servername = "localhost";
$username = "username";
$password = "password";
$database = "dbname";

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

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

echo "Connected successfully";
?>
