 * Hello,
 * I have the FPDF library in a folder called fpdf and that folder is in my custom
   plugin folder. The problem is, whenever I try to use `require('fpdf/fpdf.php');`
   to make use of it, I end up getting an error that no such file or directory exists.
   I really want to get it to work.
 * Any idea why that’s happening?

 * The request is most likely looking for the folder in relation to a differnt folder,
   so it’s not finding it. The best way to make sure that it’s going to work is 
   to use the full file path. Something like this:
 * `$file_uri = plugins_url( 'fpdf/fpdf.php', __FILE__ );`
 * That will ensure that you always get the correct URI for the file, and you can`
   echo` it out to see if it really is correct (I always like to add in some de-
   bugging in situations like this).

 * Thanks for your reply!
 * I’ve tried what you suggested and I echoed it. The path is correct however it
   still says that the file cannot be found.

 * Then the file isn’t where you think it is. If it was, the script would find it.:/

 * The plugins_url() function returns a URL. The PHP allow_url_include setting is
   usually disabled for security reasons. When the setting is disabled, attempting
   to use include() or require() on an HTTP stream will fail.
 * If the fpdf.php file is located in the /fpdf subdirectory of the plugin, placing
   the following line as the first line of code in the plugin:
 *     ```
       define('MYPLUGIN_BASE_DIR', dirname(__FILE__));
       ```
   
 * and using the following line to load the file:
 *     ```
       require(MYPLUGIN_BASE_DIR . '/fpdf/fpdf.php');
       ```
   
 * will work. You can change MYPLUGIN_BASE_DIR to whatever you want.

 * Thanks for the code! I’ll try it as soon as possible and give feedback.
