What are best practices for handling password inputs in PHP?

When handling password inputs in PHP, it is important to securely store passwords by hashing them using a strong hashing algorithm like bcrypt. This helps protect user passwords in case of a data breach. Additionally, always use prepared statements when interacting with databases to prevent SQL injection attacks. 

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

// Using prepared statements to insert hashed password into the database
$stmt = $pdo->prepare("INSERT INTO users (username, password) VALUES (:username, :password)");
$stmt->bindParam(':username', $_POST['username']);
$stmt->bindParam(':password', $hashed_password);
$stmt->execute();
