How does encrypting PHP files affect performance and debugging capabilities?

Encrypting PHP files can negatively impact performance because the server needs to decrypt the files before executing them, which can add overhead. Additionally, debugging capabilities are hindered because encrypted code is not human-readable, making it difficult to troubleshoot issues. To improve performance and maintain debugging capabilities, consider using obfuscation techniques instead of encryption. Obfuscation can make the code harder to understand while still allowing for efficient execution and easier debugging.

// Example of obfuscation using a tool like PHP Obfuscator
// Original PHP code
function helloWorld() {
    echo "Hello, World!";
}

// Obfuscated PHP code
eval(gzinflate(base64_decode('eJxTz0lPLy7J0UjVyCxRqUgtSgUA')));
