How can I create Wordpress tags programmatically?
//Define the category
$my_cat = array('cat_name' => 'My Category', 'category_description' => 'A Cool Category', 'category_nicename' => 'category-slug', 'category_parent' => '');

// Create the category
$my_cat_id = wp_insert_category($my_cat);

<?php wp_insert_term( $term, $taxonomy, $args = array() ); ?>
