You don't need {assign} for a temporary variable.

Code:
{php}
    $var = $this->get_template_vars('product');
    echo $var['id_product'];
{/php}


Anyway you should avoid using {php} tags. It's bad practise. Any good reasion that you need it?

Instead of embedding PHP in templates, write a plugin and call the plugin from within the template. Don't use {php} tags, they just cause more problems than they solve. You don't want this mess in the template, keep the template focused on presentation.
