What are some potential pitfalls of using a debugging method to track method usage, especially in older or third-party code?

Potential pitfalls of using a debugging method to track method usage in older or third-party code include: 1. The possibility of introducing performance overhead due to the added debugging code. 2. Debugging methods may not be compatible with older or third-party code, leading to errors or unexpected behavior. 3. Debugging information may expose sensitive data or implementation details. To mitigate these pitfalls, consider using a lightweight logging library specifically designed for tracking method usage in a non-intrusive manner.

// Example of using a lightweight logging library to track method usage
use Monolog\Logger;
use Monolog\Handler\StreamHandler;

// create a log channel
$log = new Logger('method_usage');
$log->pushHandler(new StreamHandler('path/to/log/file.log', Logger::INFO));

// log a message
$log->info('Method XYZ was called');
