Is there a recommended approach for verifying user credentials when using PHP for web browser logins?

When verifying user credentials in PHP for web browser logins, it is recommended to use secure hashing algorithms like bcrypt to store passwords in the database. This helps protect user passwords in case of a data breach. Additionally, always use parameterized queries to prevent SQL injection attacks when querying the database for user credentials. 

// Verifying user credentials using bcrypt hashing and parameterized queries

// Retrieve user credentials from login form
$username = $_POST['username'];
$password = $_POST['password'];

// Query the database for the user's hashed password
$stmt = $pdo->prepare("SELECT password FROM users WHERE username = ?");
$stmt->execute([$username]);
$user = $stmt->fetch();

// Verify the password using password_verify function
if ($user && password_verify($password, $user['password'])) {
    // User credentials are valid, proceed with login
    // Set session variables, redirect to dashboard, etc.
} else {
    // User credentials are invalid, show error message
}
