What are the potential risks and benefits of encrypting PHP files?

Encrypting PHP files can help protect sensitive code and data from unauthorized access, theft, and tampering. However, it can also make debugging and troubleshooting more challenging, as encrypted files cannot be easily read or modified. Additionally, encrypting PHP files may introduce performance overhead due to the decryption process. 

// Example of encrypting a PHP file using OpenSSL
$plaintext = file_get_contents('original.php');
$key = openssl_random_pseudo_bytes(32);
$iv = openssl_random_pseudo_bytes(16);
$ciphertext = openssl_encrypt($plaintext, 'aes-256-cbc', $key, 0, $iv);
file_put_contents('encrypted.php', $ciphertext);
