How can one ensure that the passwords in the wp-config.php file match the actual database access credentials?

To ensure that the passwords in the wp-config.php file match the actual database access credentials, you can create a PHP script that connects to the database using the credentials from the wp-config.php file and checks if the connection is successful. This way, you can verify that the passwords are correct and that the database access is working properly.

<?php
require_once('wp-config.php');

$mysqli = new mysqli(DB_HOST, DB_USER, DB_PASSWORD, DB_NAME);

if ($mysqli->connect_error) {
    die('Connection failed: ' . $mysqli->connect_error);
}

echo 'Connection successful! Database access credentials in wp-config.php match.';
?>
