What are the potential drawbacks and benefits of encrypting a database in PHP? How does it impact performance and security?

Encrypting a database in PHP can provide an additional layer of security by protecting sensitive data from unauthorized access. However, it can also impact performance as encryption and decryption processes can add overhead to database operations. It is important to weigh the benefits of increased security against the potential drawbacks of decreased performance when deciding whether to encrypt a database in PHP. 

// Example of encrypting data before storing it in a database
$plaintext = "Sensitive data";
$encryption_key = "supersecretkey";
$encrypted_data = openssl_encrypt($plaintext, 'AES-256-CBC', $encryption_key, 0, 'supersecretilv');

// Store $encrypted_data in the database
