drupal_bootstrap

A string describing a phase of Drupal to load. Each phase adds to the previous one, so invoking a later phase automatically runs the earlier phases too. The most important usage is that if you want to access the Drupal database from a script without loading anything else, you can include bootstrap.inc, and call drupal_bootstrap(DRUPAL_BOOTSTRAP_DATABASE).

Parameters

$phase: A constant. Allowed values are: DRUPAL_BOOTSTRAP_CONFIGURATION: initialize configuration. DRUPAL_BOOTSTRAP_EARLY_PAGE_CACHE: try to call a non-database cache fetch routine. DRUPAL_BOOTSTRAP_DATABASE: initialize database layer. DRUPAL_BOOTSTRAP_ACCESS: identify and reject banned hosts. DRUPAL_BOOTSTRAP_SESSION: initialize session handling. DRUPAL_BOOTSTRAP_LATE_PAGE_CACHE: load bootstrap.inc and module.inc, start the variable system and try to serve a page from the cache. DRUPAL_BOOTSTRAP_PATH: set $_GET['q'] to Drupal path of request. DRUPAL_BOOTSTRAP_FULL: Drupal is fully loaded, validate and fix input data.
