function hook_boot
| 7.x system.api.php | hook_boot() |
| 6.x core.php | hook_boot() |
Perform setup tasks for all page requests.
This hook is run at the beginning of the page request. It is typically used to set up global parameters that are needed later in the request.
Only use this hook if your code must run even for cached page views. This hook is called before the theme, modules, or most include files are loaded into memory. It happens while Drupal is still in bootstrap mode.
