function hook_hook_info in Drupal 9
Same name and namespace in other branches
- 8 core/lib/Drupal/Core/Extension/module.api.php \hook_hook_info()
- 7 modules/system/system.api.php \hook_hook_info()
Defines one or more hooks that are exposed by a module.
Normally hooks do not need to be explicitly defined. However, by declaring a hook explicitly, a module may define a "group" for it. Modules that implement a hook may then place their implementation in either $module.module or in $module.$group.inc. If the hook is located in $module.$group.inc, then that file will be automatically loaded when needed. In general, hooks that are rarely invoked and/or are very large should be placed in a separate include file, while hooks that are very short or very frequently called should be left in the main module file so that they are always available.
See system_hook_info() for all hook groups defined by Drupal core.
Return value
An associative array whose keys are hook names and whose values are an associative array containing:
- group: A string defining the group to which the hook belongs. The module system will determine whether a file with the name $module.$group.inc exists, and automatically load it when required.
