How to generate hyperlinks in yii framework

In actual projects, we recommend using the built-in URL tool class of Yii2 to generate links, because in this way we can very conveniently manage the URL behavior of the entire site: for example, changing the entire site by modifying the configuration URL format, etc.

Yii2 built-in URL generation tool

URL manager: urlManager

URL helper class: yii\helpers\Url

Using the built-in URL generation tool, you can beautify the URL of the entire site through configuration without changing the source code.

(Recommended tutorial: yii framework)

URL Manager

The URL manager is a built-in called urlManager Application components. In WEB applications and console applications, URLs can be created in the following two ways:

\Yii::$app->urlManager->createUrl($params)
\Yii::$app->urlManager->createAbsoluteUrl($params, $schema = null)

createUrl method generates a relative path to the root directory, for example: /index.php?r=article/view

## The #createAbsoluteUrl() method generates an absolute path, for example: http://www.example.com/index.php?r=article/view

Common examples of using URL managers to create URLs:

// URL：/index.php?r=article/view
\Yii::$app->urlManager->createUrl('article/view');
// URL：/index.php?r=article/view&id=2
\Yii::$app->urlManager->createUrl(['article/view','id'=>2]);
// URL： http://www.example.com?r=kernel/article/viewecho 
\Yii::$app->urlManager->createAbsoluteUrl('kernel/article/view');

URL Helper Class
