Drupal: What is wrong with my base_path to my libraries folder

Question

I get the following error: Warning: require_once(/libraries/recaptchalib.php): failed to open stream: No such file or directory in eval() (line 3 of /home3/quikappd/public_html/rulpon/modules/php/php.module(80) : eval()'d code).

In drupal 6 I am attempting to add captcha to an old content type that has a php html form built into it. I add the captchalib file to the library folder in my drupal instance, but I keep getting the error message noted above. I have tried dirname, base_path and various other urls to get to the folder. What am I do wrong?

This is what I had for base_path -> require_once(base_path().'libraries/recaptchalib.php'); then this for dirname -> require_once ( dirname(__FILE__) . '/libraries/recaptchalib.php'); then just straight url -> //require_once('decon.com/sites/all/libraries/recaptchalib.php');

According to base_path() doc, it returns an URL segment. For example, if the drupal site homepage is on http://www.example.com/foobar, it would return /foobar

That's why it doesn't help in locating an include file with php.

When knowing where the file is relative to document root, you may use:

require_once($_SERVER['DOCUMENT_ROOT']."/site/all/libraries/recaptchalib.php");

Or if the file is part of a module, a better method is be to locate it through:

drupal_get_path('module', 'name-of-module')
