Understanding Source Code

The best way to understand what a hook does is to look at where it occurs in the source code.

Remember, this hook may occur in more than one file. Moreover, the hook's context may change from version to version.

441  * Most of WP is loaded at this stage, and the user is authenticated. WP continues
442  * to load on the {@see 'init'} hook that follows (e.g. widgets), and many plugins instantiate
443  * themselves on it for all sorts of reasons (e.g. they need a user, a taxonomy, etc.).

445  * If you wish to plug an action once WP is loaded, use the {@see 'wp_loaded'} hook below.
