Calling Drupal functions in external PHP file

问题

How can I call a Drupal function or get the global variable in a PHP file which is located under the drupal installation folder. I doing it for the first time. Are there any files I need to include in my code in order to access the Drupal function or variables?

Taken from the linked question in the comment above

You need to Bootstrap Drupal in the external PHP file:

/** bootstrap Drupal **/
chdir("/path/to/drupal/site/htdocs");
require_once './includes/bootstrap.inc';
drupal_bootstrap(DRUPAL_BOOTSTRAP_FULL);

Be sure to change the path to your Drupal installation, then add your code below the code posted above.

If the above explained example doesn't work try this:

$path = $_SERVER['DOCUMENT_ROOT'];
chdir($path."/drupal");
define('DRUPAL_ROOT', getcwd()); //the most important line
require_once './includes/bootstrap.inc';
drupal_bootstrap(DRUPAL_BOOTSTRAP_FULL);

回答3:

define('DRUPAL_ROOT', getcwd());
require_once './includes/bootstrap.inc';
drupal_bootstrap(DRUPAL_BOOTSTRAP_FULL);

The above code works for me, when the script is in my Drupal root directory. This loads absolutely everything, not just Drupal core, including contributed module hooks.

define('DRUPAL_ROOT', getcwd());

require_once DRUPAL_ROOT . '/includes/bootstrap.inc';
drupal_bootstrap(DRUPAL_BOOTSTRAP_FULL);
global $user;
print_r($user);
