How do I create an external link using cakephp?

Question

A link of the type below serves to link to a page(view) of our own system:

<?php echo $this->Html->link('Listar todas as tarefas', array('action'=>'index')); ?>

And if I want to link to youtube for example or another site?

Answer 1

Just replace the array of the second parameter by the desired URL. Thus:

echo $this->Html->link('YouTube', 'http://www.youtube.com');
