How important is it to verify the accuracy of the host name when encountering errors like "Unknown MySQL Server Host" in PHP?

When encountering errors like "Unknown MySQL Server Host" in PHP, it is crucial to verify the accuracy of the host name specified in the database connection settings. This error typically occurs when the host name provided is incorrect or the MySQL server is not reachable. Double-checking the host name can help resolve the issue and establish a successful connection to the MySQL server. 

// Database connection settings
$host = "localhost"; // Update this with the correct host name
$username = "root";
$password = "";
$database = "my_database";

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

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

echo "Connected successfully";
