$password = 'rasmuslerdorf';
$hash = '$2y$10$YCFsG6elYca568hBi2pZ0.3LDL5wjgxct1N8w/oLR/jfHsiQwCqTS';
// The cost parameter can change over time as hardware improves
$options = array('cost' => 11);
// Verify stored hash against plain-text password
if (password_verify($password, $hash)) {
// Check if a newer hashing algorithm is available
// or the cost has changed
if (password_needs_rehash($hash, PASSWORD_DEFAULT, $options)) {
// If so, create a new hash, and replace the old one
$newHash = password_hash($password, PASSWORD_DEFAULT, $options);
