How can encrypting PHP files impact code readability and maintainability?

Encrypting PHP files can impact code readability and maintainability because it makes it difficult for developers to easily understand and modify the code. This can lead to challenges in debugging, updating, and maintaining the codebase. To address this issue, it is important to strike a balance between protecting sensitive information and maintaining code readability by using encryption techniques that allow for decryption when needed. 

// Example of using encryption and decryption in PHP
$plaintext = "Hello, World!";
$key = "secret_key";

// Encrypt the data
$encrypted = openssl_encrypt($plaintext, 'AES-128-CBC', $key, 0, $iv);

// Decrypt the data
$decrypted = openssl_decrypt($encrypted, 'AES-128-CBC', $key, 0, $iv);

echo $decrypted; // Output: Hello, World!
