I\'m familiar with remove_action
when removing an action in WordPress.
To create the action:
add_action( \'action_hook\', \'function_name\', 10, 3 );<
Inside class
add_action( 'some_action_hook', array( $this, 'some_function' ) );
Outside class,
With use of global vairable:
global $my_class;
remove_action( 'some_action_hook', array( $my_class, 'some_function' ) );
Using class name:
remove_action( 'some_action_hook', array( 'MyClass', 'some_function' ) );
Reference.
