function _phptemplate_default

Default callback for PHPTemplate.

Load a template file, and pass the variable array to it. If the suggested file is not found, PHPTemplate will attempt to use a $hook.tpl.php file in the template directory, and failing that a $hook.tpl.php in the PHPTemplate directory.

Parameters

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

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

$suggestions: An array of suggested template files to use. This may include a path when the suggested template is contained within a sub-directory of the theme. They are set from _phptemplate_variables() or the theming hook invoking _phptemplate_callback().
