Almost working: recursively pre-populate taxonomy terms

gistfile1.txt

add_action( 'init', 'sld_prepopulate' );
function sld_prepopulate() {

	$terms = array(
			'term1',
			'term2',
			'Faculty' => array(
				'booze',
				'jeans',
			),
			'other',
		);


	function sld_insert_terms( $terms, $taxonomy, $parent = 0 ) {
		$args = array( 'parent' => $parent );
		foreach ( $terms as $k => $v ) {
			if ( is_array( $v ) ) {
				echo " parent = wp_insert_term( $k, $taxonomy, $args )";
				$parent = wp_insert_term( $k, $taxonomy, $args );
				die(var_dump($parent));
				echo "sld_insert_terms( $v, $taxonomy, {$parent->term_id} )";
				sld_insert_terms( $v, $taxonomy, $parent->term_id );
			} else {
				wp_insert_term( $v, $taxonomy, $args );
			}
		}
	}


	// sld_insert_terms( $terms, 'staff-type' );
