How can PHP developers securely store and manage user passwords in databases?

To securely store and manage user passwords in databases, PHP developers should use password hashing functions like password_hash() to securely hash the passwords before storing them. This ensures that the passwords are not stored in plain text and are protected from potential security breaches. 

// Hashing the user's password before storing it in the database
$password = $_POST['password']; // Get the password from the form
$hashed_password = password_hash($password, PASSWORD_DEFAULT);

// Store the hashed password in the database
$query = "INSERT INTO users (username, password) VALUES (:username, :password)";
$stmt = $pdo->prepare($query);
$stmt->execute(array(':username' => $username, ':password' => $hashed_password));
