Doubt about helpers

Yii 2.0 General Discussions

Hello friends.

I create a helper and I put in folder "Helpers", I set the path in web/index.php:




<?php


// comment out the following two lines when deployed to production

defined('YII_DEBUG') or define('YII_DEBUG', true);

defined('YII_ENV') or define('YII_ENV', 'dev');


require(__DIR__ . '/../vendor/autoload.php');

require(__DIR__ . '/../vendor/yiisoft/yii2/Yii.php');

require(__DIR__ . '/../helpers/Utils.php'); // my helper


$config = require(__DIR__ . '/../config/web.php');


(new yii\web\Application($config))->run();

So to use in a view this is the way:

<?= yii\helpers\Utils::doSomeThing("test") ?>

Worked well, but why I need put "yii\helpers\"? I think i can use:

<?= Utils::doSomeThing("test") ?>

Is it possible?

Because of PHP namespaces. Either you’re specifying full class name including namespace or using “use” to import namespaces.
