Create WordPress Shortcodes. WordPress shortcodes are super handy, especially when handing off a WordPress-based website to a client.

Your plugin needs to be fast on its own, not depending on other plugins to do the dirty work. And if you think you need to write your own cache handling code, you are wrong. WordPress comes with everything you need to quickly implement varying degrees of data caching. WordPress implements two different caching methods: Non-persistent The data remains in the cache during the loading of the page.

Built on the great ezSQL class1 by Justin Vincent, $wpdb enables you to address queries to any table in your database, and it also helps you handle the returned data.

The $wpdb class modularizes and automates a lot of database-related tasks.
