Logging to Stdout with Monolog

My worker scripts have really basic logging (as in, they echo when something happens, and I can see those in the supervisord logs). Which is kind of okay, but I wanted to at least add timestamps in to them, and maybe send emails when something REALLY bad happened.

I’m a huge fan of Monolog so I grabbed that, but it wasn’t immediately obvious which of the many and varied options I would need for this fairly simple addition. It turns out that the right thing to use is the ErrorLogHandler, so now my code looks like this:

<?php

require "vendor/autoload.php";

$logger = new \Monolog\Logger("log");
$logger->pushHandler(new \Monolog\Handler\ErrorLogHandler());

$logger->addInfo("Something happened");

And the output is neatly in lines like this:

[2014-06-05 17:00:47] log.INFO: Something happened [] []

You can do a lot of different things with Monolog, but since I had to look up this simplest of all options, I thought I’d share.
