What are the common methods to protect PHP code for marketing purposes?

To protect PHP code for marketing purposes, one common method is to obfuscate the code, making it harder for others to understand and replicate. This can help prevent competitors from stealing your marketing strategies or techniques. Another method is to use encryption techniques to secure sensitive data within the code, such as API keys or proprietary algorithms. 

// Example of obfuscating PHP code
$code = file_get_contents('original_code.php');
$obfuscated_code = base64_encode($code);
file_put_contents('obfuscated_code.php', $obfuscated_code);

// Example of encrypting sensitive data in PHP code
$api_key = 'my_secret_api_key';
$encrypted_api_key = openssl_encrypt($api_key, 'AES-256-CBC', 'my_secret_key', 0, 'my_secret_iv');
