A simple file-based PSR-3 logging library.
- provides basic severity level filtering
- can be used as a singleton
- also with multiple logs
- able to serialize arrays and objects (first tries with
__toString()
, then appliesjson_encode()
) - supports placeholders (see PSR-3)
- compatible with all PSR-3 releases from 1 on
