WordPress Hooks Database

What are hooks? WordPress hooks allow you (via a plugin) to change WordPress's behavior without editing any core files. This database automatically scans each WP build for apply_filters(), apply_filters_ref_array(), do_action(), and do_action_ref_array to identify all the hooks available in each WP build and show them in context.
