Are there any best practices for securely handling login credentials in PHP?

Storing login credentials securely is crucial to prevent unauthorized access to user accounts. One best practice is to hash passwords using a strong hashing algorithm like bcrypt before storing them in the database. Additionally, using prepared statements to prevent SQL injection attacks when querying the database for user credentials is important. 

// Hashing the password before storing it in the database
$password = 'user_password';
$hashed_password = password_hash($password, PASSWORD_BCRYPT);

// Verifying the hashed password during login
$login_password = 'user_login_password';
if (password_verify($login_password, $hashed_password)) {
    // Password is correct
} else {
    // Password is incorrect
}

// Using prepared statements to query the database for user credentials
$stmt = $pdo->prepare('SELECT * FROM users WHERE username = :username');
$stmt->bindParam(':username', $username);
$stmt->execute();
$user = $stmt->fetch();
