Referral URL in php
<p>So I am trying to get the page where a visitor came from. I inserted this code into a php file and I am trying to see the page's URL but it is not working, any suggestions?</p>

<pre><code>&lt;?php 

  $ref = getenv("HTTP_REFERER"); 
  echo $ref; 

?&gt;
</code></pre>

<p>(added this after some answers)
I have also tried</p>

<pre><code>print $_SERVER["HTTP_REFERER"];
</code></pre>

<p>and that doesn't work either</p>

<p>it worked after i updated the website many times, not sure why was there a problem in the first place, thanks anyway :) </p>
