Is it necessary to encrypt personally identifiable information in the database in PHP applications?

It is highly recommended to encrypt personally identifiable information in the database in PHP applications to enhance security and protect sensitive data from unauthorized access. This can be achieved by using encryption algorithms like AES or bcrypt to securely store data in the database. 

// Encrypting personally identifiable information before storing in the database
$plaintext = "John Doe";
$key = "secret_key";
$encrypted_data = openssl_encrypt($plaintext, 'aes-256-cbc', $key, 0, '1234567890123456');

// Storing the encrypted data in the database
$stmt = $pdo->prepare("INSERT INTO users (name) VALUES (:name)");
$stmt->bindParam(':name', $encrypted_data);
$stmt->execute();
