Levels - Slim — ContextQMD

<div class="alert alert-info"> <strong>Heads Up!</strong> Use the <code>\Slim\Log</code> constants when setting the log level instead of using raw integers. </div>

The Slim application’s log object will respect or ignore logged messages based on its log level setting. When you invoke the log object’s methods, you are inherently assigning a level to the logged message. The available log levels are:

\Slim\Log::EMERGENCY : Level 1

\Slim\Log::ALERT : Level 2

\Slim\Log::CRITICAL : Level 3

\Slim\Log::ERROR : Level 4

\Slim\Log::WARN : Level 5

\Slim\Log::NOTICE : Level 6

\Slim\Log::INFO : Level 7

\Slim\Log::DEBUG : Level 8

Only messages that have a level less than the current log object’s level will be logged. For example, if the log object’s level is \Slim\Log::WARN (5), the log object will ignore \Slim\Log::DEBUG and \Slim\Log::INFO messages but will accept \Slim\Log::WARN, \Slim\Log::ERROR, and \Slim\Log::CRITICAL messages.

How to set the log level

<?php
$app->log->setLevel(\Slim\Log::WARN);

You can set the log object’s level during application instantiation, too:

<?php
$app = new \Slim\Slim(array(
    'log.level' => \Slim\Log::WARN
));
