_phptemplate_callback

Execute a template engine call.

Each call to the template engine has two parts. Namely preparing the variables, and then doing something with them.

The first step is done by all template engines / themes, the second step is dependent on the engine used.

Parameters

$hook: The name of the theme function being executed.

$variables: A sequential array of variables passed to the theme function.

$file: A suggested template file to use. If the file is not found, the default $hook.tpl.php will be used.

Return value

The HTML generated by the template system.
