<?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")); ?>
