Detailed Description

The "Categoryfinder" class takes a list of articles, creates an internal representation of all their parent categories (as well as parents of parents etc.).

From this representation, it determines which of these articles are in one or all of a given subset of categories.

Example use : # Determines whether the article with the page_id 12345 is in both # "Category 1" and "Category 2" or their subcategories, respectively

$cf = new Categoryfinder; $cf->seed( array( 12345 ), array( 'Category 1', 'Category 2' ), 'AND' ); $a = $cf->run(); print implode( ',' , $a );
