How to print string to console Yii2

I am really new to Yii2 and I am trying to print a simple string to the console. However, no matter what I do, I can’t really make it work. I am not sure if I have my Setup wrong or if I simply don’t use the functions as intended.

My TeamController.php was generated by Gii and the function I want to simply check if my code runs through looks like this:

<?php

namespace appcontrollers;

use Yii;
use appmodelsTeam;
use yiidataActiveDataProvider;
use yiiwebController;
use yiiwebNotFoundHttpException;
use yiifiltersVerbFilter;
use yiilogLogger;
use yiihelpersVarDumper;

    /**
     * Creates a new Team model.
     * If creation is successful, the browser will be redirected to the 'view' page.
     * @return mixed
     */
    public function actionCreate()
    {
        VarDumper::dump('Hello world'); //<-- Does not print to console.
        Yii::debug('start calculating average revenue'); //<-- Does not print to console.
        $model = new Team();
        if ($this->request->isPost) {
            if ($model->load($this->request->post()) && $model->save()) {
                return $this->redirect(['view', 'idteam' => $model->id]);
            }
        } else {
            $model->loadDefaultValues();
        }

        return $this->render('create', [
            'model' => $model,
        ]);
    } 

UPDATE

Changed some configurations in the web.php within the config directory.:

'log' => [
            'targets' => [
                [
                    'class' => 'yiilogFileTarget',
                    'levels' => ['error', 'warning', 'trace', 'info'],
                    'logVars' => [],
                    'logFile' => '@runtime/webapp/logs/myfile.log',
                ],
            ],
        ], 

Am I forgetting something or are other configurations wrong?

Answer

You can try to set flushInterval and exportInterval

'log' => [
    'flushInterval' => 1, // <-- here
    'targets' => [
        [
            'class' => 'yiilogFileTarget',
            'levels' => ['error', 'warning', 'trace', 'info'],
            'logVars' => [],
            'logFile' => '@runtime/webapp/logs/myfile.log',
            'exportInterval' => 1, // <-- and here
        ],
    ],
]
