Best way to integrate

[eluser]Gewa[/eluser]
Hi, there is a service that needs to be integrated in my site to show links .
So here what they say I need to do.

define a global variable

Code:

define('LINKFEED_USER', '597a420cb42bbb3148b53cd2663609f1769b1891');
   require_once($_SERVER['DOCUMENT_ROOT'].'/'.LINKFEED_USER.'/linkfeed.php');
   global $linkfeed;
   $linkfeed = new LinkfeedClient();

then use this code to show links

Code:

global $linkfeed;
   echo $linkfeed->return_links(1);

What is the best way to make it?
