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
public Psr\Log\AbstractLogger :: alert ( $message , array $context = [ ] )

Example: Entire website down, database unavailable, etc. This should
trigger the SMS alerts and wake you up.

public Psr\Log\AbstractLogger :: critical ( $message , array $context = [ ] )
 

Critical conditions.

Example: Application component unavailable, unexpected exception.

  • return void
public Psr\Log\AbstractLogger :: debug ( $message , array $context = [ ] )
 

Detailed debug information.

  • return void
public Psr\Log\AbstractLogger :: emergency ( $message , array $context = [ ] )
 

System is unusable.

  • return void
public Psr\Log\AbstractLogger :: error ( $message , array $context = [ ] )
 

Runtime errors that do not require immediate action but should typically
be logged and monitored.
