Describes a logger instance.

The message MUST be a string or object implementing __toString().

The message MAY contain placeholders in the form: {foo} where foo
will be replaced by the context data in key "foo".

The context array can contain arbitrary data. The only assumption that
can be made by implementors is that if an Exception instance is given
to produce a stack trace, it MUST be in a key named "exception".

See https://github.com/php-fig/fig-standards/blob/master/accepted/PSR-3-logger-interface.md
for the full interface specification.

Abstract Interface
Methods
public abstract alert ( Stringable | string $message , array $context = [ ] ) : void
 

Action must be taken immediately.

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

  • param string | Stringable $message
  • param array $context
  • return void
public abstract critical ( Stringable | string $message , array $context = [ ] ) : void
 

Critical conditions.

Example: Application component unavailable, unexpected exception.

  • param string | Stringable $message
  • param array $context
  • return void
public abstract debug ( Stringable | string $message , array $context = [ ] ) : void
 

Detailed debug information.

  • param string | Stringable $message
  • param array $context
  • return void
public abstract emergency ( Stringable | string $message , array $context = [ ] ) : void
 

System is unusable.

  • param string | Stringable $message
  • param array $context
  • return void
public abstract error ( Stringable | string $message , array $context = [ ] ) : void
 

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

  • param string | Stringable $message
  • param array $context
  • return void
public abstract info ( Stringable | string $message , array $context = [ ] ) : void
 

Interesting events.

Example: User logs in, SQL logs.

  • param string | Stringable $message
  • param array $context
  • return void
public abstract log ( $level , Stringable | string $message , array $context = [ ] ) : void
 

Logs with an arbitrary level.

public abstract notice ( Stringable | string $message , array $context = [ ] ) : void
 

Normal but significant events.

  • param string | Stringable $message
  • param array $context
  • return void
public abstract warning ( Stringable | string $message , array $context = [ ] ) : void
 

Exceptional occurrences that are not errors.

Example: Use of deprecated APIs, poor use of an API, undesirable things
that are not necessarily wrong.

  • param string | Stringable $message
  • param array $context
  • return void
