How can encrypting PHP source code protect intellectual property rights of algorithms?

Encrypting PHP source code can protect intellectual property rights of algorithms by making it difficult for unauthorized users to access and understand the code. This can help prevent plagiarism or theft of algorithms, as the encrypted code would be unreadable without the proper decryption key. This can be achieved using tools like ionCube or Zend Guard to encode the PHP source code.

// Sample code using ionCube to encrypt PHP source code
// This is just an example and actual implementation may vary

// Encrypt the PHP source code using ionCube
ioncube_encoder_run("source_code.php", "encrypted_code.php");
