WordPress Hook

WordPress has hundreds of hooks, and it's hard to give an exact number. However, I can provide you with an overview of the different types of hooks and some examples of popular ones.

Types of Hooks:

1. Action Hooks: These allow you to execute a function at a specific point in WordPress's execution. Examples: wp_footer, admin_init, wp_login.
2. Filter Hooks: These allow you to modify data before it's used or displayed. Examples: the_content, wp_title, get_avatar.
3. Shortcode Hooks: These allow you to create custom shortcodes. Examples: [gallery-pro], [contact-formetc].
4. Widget Hooks: These allow you to create custom widgets. Examples: wp_widget_archives, wp_widget_categories.
