Drupal module A Drupal module is a collection of files containing some functionality and is written in PHP.

In fact, a module is no different from a regular PHP file that can be independently created and tested and then used to drive multiple functionalities.
- 4. This approach allows Drupal core to call at specific places certain functions defined in modules and enhance the functionality of core. The places where code can be executed are called "hooks" and are defined by a fixed interface. Hooks Drupal modules work on a event like system called hooks. A hook is a way for you to place a piece of your own custom code to be run by Drupal at a very specific time. Using hooks, you can ask Drupal to run a piece of your code precisely when a comment is viewed, or a node is edited or a search result is displayed. You don't actually create hooks. You use helper functions such as module_invoke_all(), module_invoke() or drupal_alter() to invoke all functions matching the expected name pattern. The invoked functions are usually found with module_implements().
