How can I include a PHP file located in my Drupal's home directory from a module?

3 Answers 3


Drupal 7 defines the constant DRUPAL_ROOT, which contains the name of the directory where Drupal is installed. It is used from Drupal functions, such as module_load_include() in a way similar to the following one:

if (function_exists('drupal_get_path')) {
  $file = DRUPAL_ROOT . '/' . drupal_get_path('module', $module) . "/$name.$type";
  if (is_file($file)) {
    require_once $file;
    return $file;

In your case, you should use the following code:

require_once DRUPAL_ROOT . "/$filename";

The variable $filename contains the name of the file to load.


If I understand well, according my test is not needed indicate any path, just with the name of your file that is in your home directory. For example I have a file called testfile.php in my home directory, then from my module inside sites/all/modules I can use:

include ('testfile.php');

I hope information be useful.


I would use API module_load_include().

Edit : This API is meant for including PHP file located in module's directory.

  • You cannot use module_load_include() because the function looks for the file in a module's directory. The OP is asking about a file that is in the directory where Drupal is installed (what the OP calls "Drupal's home directory").
