Functions
| Name | Description |
|---|---|
| bootstrap_hooks | Define the critical hooks that force modules to always be loaded. |
| bootstrap_invoke_all | Call all init or exit hooks without including all modules. |
| check_plain | Encode special characters in a plain-text string for display as HTML. |
| conf_init | Loads the configuration and sets the base URL, cookie domain, and session name correctly. |

| drupal_autoload_class | Confirm that a class is available. |
| drupal_autoload_interface | Confirm that an interface is available. |
| 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... |
| drupal_function_exists | Confirm that a function is available. |
| drupal_get_bootstrap_phase | Return the current bootstrap phase for this Drupal process. The current phase is the one most recently completed by drupal_bootstrap(). |
| drupal_get_filename | Returns and optionally sets the filename for a system item (module, theme, etc.). The filename, whether provided, cached, or retrieved from the database, is only returned if the file exists. |
| drupal_get_messages | Return all messages that have been set. |
| drupal_get_schema | Get the schema definition of a table, or the whole database schema. |
| drupal_init_language | Choose a language for the current page, based on site and user preferences. |
| drupal_is_denied | Check to see if an IP address has been blocked. |

| get_t | Return the name of the localisation function. Use in code that needs to run both during installation and normal operation. |
| ip_address | If Drupal is behind a reverse proxy, we use the X-Forwarded-For header instead of $_SERVER['REMOTE_ADDR'], which would be the IP address of the proxy server, and not the client's. If Drupal is run in a cluster we use the... |
| language_default | Default language used on the site |
