title: Yii2 - Log files (app.log) and how to access them?
body: <p>I have a question about logs in Yii2. I want to <br><br>
  1.) Access log file (both basic/advanced application) <br>
  2.) Parse them using by using regular expressions (separate each part of the log, i partly know, how to do it) <br>
  3.) Display them by using widget (in widget i want to specify, what i want 2 show ) <br><br>
  Right now, i am struggling, which method to use, when i want to handle those logs. I know they are in : <code>app\frontend|backend|console\runtime\logs\app.log</code>, but since i am still Yii2 newbie, i don`t really know, how to perform actions like that. Every answer will be appreciated ! Thank you</p>
