Create a link with Drupal 8 like l() and url() on D7

Exemple:

use Drupal\Core\Url;



// Internal path (defined by a route in Drupal 8).

$url = Url::fromRoute('help.page.views');

$internal_link = \Drupal::l(t('Views Help Page'), $url);



// External Uri.

$url = Url::fromUri('http://www.example.com/');

$external_link = \Drupal::l(t('External link'), $url);

Update:

The l() function \Drupal::l() is deprecated.

Use \Drupal\Core\Link instead

Example:

use \Drupal\Core\Link;

$link = Link::fromTextAndUrl($text, $url);

#OR

$link = \Drupal\Core\Link::fromTextAndUrl($text, $url);
