Can you Control the Order of Hooks "Firing" in Drupal?

If two modules implement the same hook in Drupal, does the system have a way to define which order the hook functions are called, or is it just luck of the draw/alphabetical or开发者_如何学编程dering? Or something else? Or does my question show I misunderstand hooks in some fundamental way that makes me look dumb?

The order is determined based on the weight setting for the module in the system table. If two modules have the same weight, the order is alphabetical.

Take a look at module weight in database, or use http://drupal.org/project/moduleweight
