How to include php file in drupal 7

I'm coding a form in Drupal 7, and I want to 'include' a php file that adds my DB connection variables to my code.

I've tested my code in several ways, and I'm sure that the 'include' makes me get a WSOD when I run Cron in my site.

I've Googled about this and I tried:

include("/sites/all/libraries/php/connection.inc");

include("./sites/all/libraries/php/connection.inc");

include"./sites/all/libraries/php/connection.inc";

I also tried the above with '.php' extension.

And my last try:

define('__ROOT__', dirname(dirname(__FILE__)));
include(__ROOT__.'/sites/all/libraries/php/connection.inc');

Sometimes I get a WSOD when trying to run Cron, and sometimes my page styles get broken when I submit a form.

What is the correct way to include a PHP file manually in Drupal? Note that I don't want to use the 'Drupal way' to do this or to use the webform module. I want to code it manually with PHP.

In my opinion these are correct Drupal (7) ways to include code:

  1. module_load_include(); function - Drupal API documentation - to include any PHP files from within your or other modules where needed,
  2. files[] = ... in your_module.info file to autoload include classes and interfaces within your own module - Writing .info file documentation.

Libraries module provides it's own way to include external PHP files from the libraries.

The second answer is the correct "Drupal way". The one that was accepted as the answer has many potential pitfalls if locations of things change. Using drupal_get_path is the best way. This is also especially true if you are trying to include a file that may not be fully bootstrapped during a module update hook.

The libraries directory should only be used to store files shipped as a library through the libraries module (see here https://drupal.org/project/libraries).

For both examples lets assume library.inc is our file and relative_path_to is the relative path based on the module directory to our library.inc file.

To just include a file you can use:

require(drupal_get_path('module', 'module_name') . '/relative_path_to/library.inc');

And to do it the Drupal way (https://api.drupal.org/api/drupal/includes!module.inc/function/module_load_include/7):

module_load_include('inc', 'module_name', '/relative_path_to/library');

Try this ways

1) require 'includes/iso.inc';
2) include_once  'includes/iso.inc';
3) include ('includes/iso.inc');

OR Drupal Ways

include_once DRUPAL_ROOT . '/includes/iso.inc';
