A simple PHP logger class for logging out to a specified file.
Log levels can be one of the following:
INFO DEBUG WARN ERROR FATAL
Output is only written to file if the log level is within the scope of the level specified when instantiating the logger (e.g. a info call would not be written if the log level was set to WARN).
$logger = new Logger("development.log", Logger::INFO);
# would create a new log file at /path/to/logger/script/log/development.log
$logger->info("Why hello there Ted");
# writes "Why hello there Ted" to development.log
