MyLogger is a project I started for my own C++ basedprojects. Output streams can be added to the logger to log to multiple outputs. Furthermore the logger has a verbosity level and also a special macro to log only once every 'n' times.
phpLogFacility is a log class for PHP (like log4j for java or the dead log4php projects here), which enables you to use an easy to use logging mechanism inside your console or web script without the need of ugly debug screen output.
