I have a problem with implementation of logging system based on PSR-3 standards (and interfaces/classes delivered with it - https://github.com/php-fig/log).

I have created some classes extending PSR-3: logger, which uses adapters to do actual logging (logger class stores adapter instance and calls log() method in it) and I came to file adapter (adapter that writes log messages into file(s)) and I'm looking for some way to implement custom log line formats. I mean that I could log messages as

[01/01/2013 12:00:00] NOTICE: Log message content\n

as well as

user: Log message content (NOTICE) ~ 01-01-2013

(complete custom order and contents)

Also, I would like to create separate class for that.

Is there any way to do it in very get-at-able way, so others (even low-skilled phpers) won't have problem with changing this?

  • No matter how "get-at-able" you write it, people will find a way to screw it up. Worrying about low-skill coders reading your code is a waste of time. – Waleed Khan Feb 16 '13 at 21:51
  • Okay, so I was thinking about something like an array of elements (as key => value) and message format as something like '[{date}] {level}: {message}\n'. Message string would replace '{message}' tag, log level '{level}' tag, and the rest would be custom. Also for dynamic values (like date) i would have to check if value is callable. Do you think it is good idea? – Sebastian Potasiak Feb 16 '13 at 21:59

Maybe it is mainstream, but have you looked at Monolog

You could implement HandlerInterface instead of LoggerInterface. Formatting would be solved by Monolog using your pattern.

This solution is also better as you can use ONE Logger and many Handlers in Monolog.

There is one downside/upside (you decide): you have to implement your level logging in the handler, which might be a bit ugly.
