Formatting Messages

When using dot-log or laminas-log, the logged value is not limited to a string. Arrays can be logged as well. For better readability, these arrays can be serialized. Laminas Log provides String, XML, JSON and FirePHP formatting.

The formatter accepts following parameters:

name - the formatter class (it must implement Laminas\Log\Formatter\FormatterInterface)
options - passed to the formatter constructor if required

The following snippet formats the message as JSON data:

'formatter' => [
    'name' => \Laminas\Log\Formatter\Json::class,
],
