NullLogger
extends AbstractLogger
in package
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.
