How to include PHP calls in templates?

[OK3]

I'm using h2o to parse and display templates within Kohana 3
framework. That's all well and good..
..but I'd like to include some php calls into my templates - e.g. to
call some helper functions like

// template.tpl
{% block content %}
<p>Hello, {{ username }}</p>
<p><?php echo HTML::anchor('/', 'Home'); ?></p>
{% endblock %}

How can I do that? I understand this may go against the templating
philosophy at all, but I don't want to sacrifice the framework's view-
related helper methods..

Thx for advice!

{{ 'home' | links_to '/' }}

Taylor, thanks for your reply!

I'm afraid this is not solution I'm looking for. The link helper was
only an example. I know there are many helper functions in H2O, but
there are also many helper function s in the framework (Kohana, Zend
etc.). I was simply asking whether there is a way how to call *any*
PHP (class) function in the template.

There may be 2 solutions:
1) I can somehow run PHP code in the templates - but I don't know how
(this is what I asked for)
2) I could extend H2O class with some more helper functions that
simply wrap the framework's functions (this seems weird :)

You can register existing help into H2o as a filter by adding a callable type , see h2o/filters.php source code for detail

Example:

H2o::AddFilter('anchor', array('HTML', 'anchor'))

{{ '/' | anchor 'home' }}

Cool, I added new class to filters (h2o/filters.php):

class KohanaFilters extends FilterCollection {
static function anchor($link, $text, $attributes=null,
$protocol=null) {
return HTML::anchor($link, $text, $attributes, $protocol);
}
}
/* Add some Kohana filters */
h2o::addFilter(array('KohanaFilters'));

In template:

{{ '/controller/action' | anchor 'My action' }}

Well this works, however, I see two problems:
1) The helper HTML::anchor() returns string which includes HTML tags
and the tag boundaries '<' and '>' get escaped (htmlspecialchars?)
2) I need to pass an array of attributes to the 'anchor' filter - how?

{{ '/' | anchor 'Home', *array_of_attributes* }}

Luke, I've also tried what you suggested:

H2o::AddFilter('anchor', array('HTML', 'anchor'))

This escapes htmlspecialchars too. And I still need to pass an array
somehow.

Is there a solution? I really appreciate your help and patience! :-)
