Turn a string, list, or array of category IDs and/or slugs into a list of links to those categories.

These are all valid calls:

<?php linkify_categories(43); ?>
<?php linkify_categories("43"); ?>
<?php linkify_categories("books"); ?>
<?php linkify_categories("43 92 102"); ?>
<?php linkify_categories("book movies programming-notes"); ?>
<?php linkify_categories("book 92 programming-notes"); ?>
<?php linkify_categories("43,92,102"); ?>
<?php linkify_categories("book,movies,programming-notes"); ?>
<?php linkify_categories("book,92,programming-notes"); ?>
<?php linkify_categories("43, 92, 102"); ?>
<?php linkify_categories("book, movies, programming-notes"); ?>
<?php linkify_categories("book, 92, programming-notes"); ?>
<?php linkify_categories(array(43,92,102)); ?>
<?php linkify_categories(array("43","92","102")); ?>
<?php linkify_categories(array("book","movies","programming-notes")); ?>
<?php linkify_categories(array("book",92,"programming-notes")); ?>

Examples:

<?php linkify_categories("43 92"); ?>

Displays something like: Books, Movies

<?php linkify_categories("43, 92", "<li>", "</li>", "</li><li>"); ?></ul>

Displays something like:

• Books
• Movies

<?php linkify_categories(""); // Assume you passed an empty string as the first value ?>

Displays nothing.

<?php linkify_categories("", "", "", "", "", "No related categories."); // Assume you passed an empty string as the first value ?>

Displays: No related categories.
