Parse template in PHP file?

[Interferon]

I want to insert the user hovercard template into a PHP page.  In an HTML page it would be done like this:

{parse template="userHoverCard" group="global" params="$author"}

This produces an error when inserted in a PHP page.  How can I correctly include templates like this in PHP, in IP.Content?

So how is this done?
