Answer 1

{php} has been deprecated. Have a look at Extending Smarty With Plugins.

put the follwing in …/plugins/function.yourplugin.php:

<?php
function smarty_function_yourplugin(array $params, Smarty_Template_Instance) {
    include 'your_other_file.php';
}

and use in your template:

{yourplugin}

Answer 2

You shouldn't add PHP code to the template. It will make whole idea of templates spoiled.

You have to add PHP code to controller, not template.
