The PHP Hooks Class is a fork of the WordPress filters hook system rolled in to a class to be ported into any php based system

• This class is heavily based on the WordPress plugin API and most (if not all) of the code comes from there.

Simple, Include the class file in your application bootstrap (setup/load/configuration or whatever you call it) and start hooking your filter and action hooks using the global $hooks. Ex:

$hooks = new Neo\Hooks\Hook;

$hooks->add_action('header_action','echo_this_in_header');

function echo_this_in_header(){
   echo 'this came from a hooked function';
}

Or you can alternatively call the added functions like you would on wordpress

add_action('header_action','echo_this_in_header');

function echo_this_in_header(){
   echo 'this came from a hooked function';
}

do_action('action');

You can also install it using composer, by adding "neo/hooks" : "dev-master" to your composer.json file. You can refer to WordPress API documentation on how to use the hook functionality.
