NullLogger
class NullLogger extends AbstractLogger (View source)
This Logger can be used to avoid conditional log calls.
Logging should always be optional, and if no logger is provided to your
library creating a NullLogger instance to have something to throw logs at
is a good way to avoid littering your code with if ($this->logger) { }
blocks.
Methods
Action must be taken immediately.
Runtime errors that do not require immediate action but should typically be logged and monitored.
Exceptional occurrences that are not errors.
Normal but significant events.
Detailed debug information.
Logs with an arbitrary level.
