Execute functions hooked on a specific action hook.
This function invokes all functions attached to action hook $tag. It is possible to create new action hooks by simply calling this function, specifying the name of the new hook using the $tag parameter.
You can pass extra arguments to the hooks, much like you can with apply_filters().

ksort($wp_filter[$tag]);
$merged_filters[ $tag ] = true;

if ( !is_null($the_['function']) )
call_user_func_array($the_['function'], array_slice($args, 0, (int) $the_['accepted_args']));
} while ( next($wp_filter[$tag]) !== false );
array_pop($wp_current_filter);
}
