If you don't know yet what is composer, have a look [on introduction](http://getcomposer.org/doc/00-intro.md). ``` composer require bartlett/monolog-callbackfilterhandler ``` Support ------- [](#support) - release 1.0.0 is not maintained except for bug report, and will accept only Monolog v1. - release 2.0.0 is the current active version, and accept only Monolog v2 Documentation ------------- [](#documentation) - release 1.0.0 is fully documented at Features -------- [](#features) - This handler obey first to basic Monolog rules as `handler level` and `bubble`. - Then, in second time, logs are filtered by rules defined in one or more callback functions. Main difference with [FilterHandler](https://github.com/Seldaek/monolog/blob/master/src/Monolog/Handler/FilterHandler.php)included in standard Monolog distribution since version 1.8.0 - `FilterHandler` can just filter records and only allow those of a given list of levels through to the wrapped handler. - `CallbackFilterHandler` may filter records to the wrapped handler, on each standard record elements including extra data and logging context. Example ------- [](#example) Here is a basic setup to log all events to a file and most important to another one (or notify by mail). See [examples/basic.php](https://github.com/llaville/monolog-callbackfilterhandler/blob/master/examples/basic.php) file.
