You could use something like:

function getTheLink() {
    App::import('Helper', 'Html');
    $this->Html = new HtmlHelper();

    return $this->Html->link('The link', '/');
}

However, if possible, I would avoid this approach and use what I described in the article ;-)

Is it possible to request a helper inside a helper’s method? Same as you would do in a controller’s action instead of the entire controller?

function getTheLink() {
var $helpers[] = ‘Html’;

return $this->Html->link(‘The link’, ‘/’);
}
