[SOLVED] Predefined Variables Question?

[phpQuestioner]

Which predefined variables is it that will let me just echo the domain of the person who is visiting referred from? I know I can do this: $_SERVER['HTTP_REFERER']; but that will display the full address path. I want to only be able to see this:  www.domain.com. I used to know how to do this; but I have forgotten how. Any body remember which predefined variable this is?

Use parse_url  PHP function to get the domain.

OK - I figured it out

 

Thank You dzysyak

 

<?php

  $fowarded = $_SERVER['HTTP_REFERER'];
  $url = "$fowarded";
  $parts = parse_url($url);

// use as needed
// print "http://";

  print $parts["host"];
