Details

cleanupEmptyCategories.php is a maintenance script to clean up empty categories in the category table. This script will clean up the category table by removing entries for empty categories without a description page and adding entries for empty categories with a description page. It will print out progress indicators every batch. The script is perfectly safe to run on large, live wikis, and running it multiple times is harmless. You may want to use the throttling options if it's causing too much load; they will not affect correctness.

If the script is stopped and later resumed, you can use the --mode and --begin options with the last printed progress indicator to pick up where you left off. When the script has finished, it will make a note of this in the database, and will not run again without the --force option.

Usage

php cleanupEmptyCategories.php [--mode] [--begin] [--throttle]

Option/Parameter	Description
--mode	"add" to empty categories with description pages, "remove" to empty categories without description pages or "both" to actually do both. Default: both
--begin	Only do categories whose names are alphabetically after the provided name
--throttle	Wait this many milliseconds after each batch. Default: 0

Example

php cleanupEmptyCategories.php --mode=add

This adds entries for empty categories with a description page.
