What is the recommended method to determine the name of a database using PHP when having access to the host, user, and password?

To determine the name of a database using PHP when having access to the host, user, and password, you can use the mysqli_connect() function to establish a connection to the MySQL server, and then use the mysqli_get_server_info() function to retrieve the database name from the server information. 

<?php
$host = "localhost";
$user = "username";
$password = "password";

// Create a connection to the MySQL server
$conn = mysqli_connect($host, $user, $password);

// Check connection
if (!$conn) {
    die("Connection failed: " . mysqli_connect_error());
}

// Get the database name from the server information
$databaseName = mysqli_get_server_info($conn);

echo "The database name is: " . $databaseName;

// Close the connection
mysqli_close($conn);
?>
