note 44733 added to function.explode

I find this function incredibly useful. I used to create a function called iReferrer(). What iReferrer() does is display an 'Intelligent Referrer'. This is my code: <?php //function_defs.php function iReferrer(){ $split = explode(".", $_SERVER['HTTP_REFERRER']); echo $split[1]; } ?> <?php //other_page.php include("function_defs.php"); // other content iReferrer() ?> If the HTTP_REFERRER was 'http://www.google.com', iReferrer() would display The word 'google' as it splits the referrer using the 'dots' from the URL. ---- Manual Page -- http://www.php.net/manual/en/function.explode.php Edit -- http://master.php.net/manage/user-notes.php?action=edit+44733 Delete -- http://master.php.net/manage/user-notes.php?action=delete+44733&report=yes Reject -- http://master.php.net/manage/user-notes.php?action=reject+44733&report=yes Search -- http://master.php.net/manage/user-notes.php
