function drupal_bootstrap in Drupal 4

Same name and namespace in other branches

1. 5 includes/bootstrap.inc \drupal_bootstrap()
2. 6 includes/bootstrap.inc \drupal_bootstrap()
3. 7 includes/bootstrap.inc \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 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_DATABASE: initialize database layer. DRUPAL_BOOTSTRAP_SESSION: initialize session handling. DRUPAL_BOOTSTRAP_PAGE_CACHE: load bootstrap.inc and module.inc, start the variable system and try to serve a page from the cache. DRUPAL_BOOTSTRAP_FULL: Drupal is fully loaded, validate and fix input data.
