printer-friendly: what's wrong?

This issue is a recap of this thread on forums.webdeveloper.com

You guys are so active here, perhaps, you can help me!

CANNOT FIGURE OUT THE PROBLEM:

same html page, same php script uploaded to different domains on the same server: one is working, the other one is not:

WORKING ON THE FIRST DOMAIN - brings the pfv page beautifully
NOT WORKING ON THE SECOND DOMAIN - echoes the referer url, so it's not totally failing, but just doesn't grab the .
WORKING EXPERIMENT WITH CROSS-DOMAINS- html page reside on first domain, referring to php code on second domain (same domain I can't get to working in example 2)

(ignore "dirty" html page, it's an inherited site, I'll get to cleaning when I can)

I don't understand, why same thing will work on one domain and wouldn't work on the other, and work again if cross-domained. Files were all uploaded in the same mode, all the server settings are applicable to both domains.... I just don't get it!
Somebody, give me a clue! I kinda need to resolve it ASAP, since I'll have to clean over 400 pages and make them all printer-friendly-enabled before week's end...

here is the php code (taken and adapted from HotScripts):

<?php 

$fd= fread(fopen($HTTP_REFERER, "r"), 100000);   

if ($fd)   

        {   

    $start= strpos($fd, "<!-- CONTENT -->");   

    $finish= strpos($fd, "<!-- /CONTENT -->");   

    $length= $finish-$start;   

    $code=Substr($fd, $start, $length);   

    }   


echo '<html> 
<head> 
    <title>CRI: Printer-Friendly Version</title> 
</head> 
<body leftmargin="0" topmargin="0" rightmargin="0" bottommargin="0" marginwidth="0" marginheight="0"> 
'.$code.' 
<br>
<hr noshade size="1">
<div style="font-family:Verdana,Arial; font-size:10px; color:#999999">'.$HTTP_REFERER.'<br>&nbsp;</div>
<hr noshade size="1">
</body> 
</html>';   

?>

adding $HTTP_REFERER = $_SERVER['HTTP_SERVER']; makes no difference.

here is a little sample html:

<html>
<head>
<title>pfv test</title>
<meta>
</head>
<body>
<a href="cri_pfv.php">Printer-friendly version</a> 
<p>this text should not be visible</p>
<!-- CONTENT --><p>and now printer-friendly version</p><!-- /CONTENT -->
</body>
</html>

I also tried different php code (for example, from mikenew.net)
Somebody, help me figure this out!!! Thanks!
