PHP 5.3+ micro logging class that can be extended via closures. Includes several pre-built handlers including file, mail, syslog, HTTP post, and MongoDB.

Analog also comes with over a dozen pre-written handlers in the Analog/Handlers folder, with examples for each in the examples folder. These include:

- Amon - Send logs to the Amon server monitoring tool
- Buffer - Buffer messages to send all at once (works with File, Mail,
Stderr,
and Variable handlers)
- ChromeLogger - Sends messages to Chrome Logger browser plugin
- File - Append messages to a file
- FirePHP - Send messages to FirePHP browser plugin
- GELF - Send message to the Graylog2 log management server
- LevelBuffer - Buffer messages and send only if sufficient error level
reached
- Mail - Send email notices
- Mongo - Save to MongoDB collection
- Multi - Send different log levels to different handlers
- Null - Do nothing
- Post - Send messages over HTTP POST to another machine
- Stderr - Send messages to STDERR
- Syslog - Send messages to syslog
- Threshold - Only writes log messages above a certain threshold
- Variable - Buffer messages to a variable reference.
So while it's a micro class, it's highly extensible and very capable out of the box too.
