How can one troubleshoot and resolve the "access denied" error in PHPMyAdmin?

To troubleshoot and resolve the "access denied" error in PHPMyAdmin, you can check the database user's permissions and ensure they have the necessary privileges to access the database. Additionally, you can try resetting the user's password or creating a new user with the correct permissions.

// Example code to troubleshoot and resolve "access denied" error in PHPMyAdmin
$servername = "localhost";
$username = "your_username";
$password = "your_password";
$dbname = "your_database";

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

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