Printer-Friendly Version generation problem

[Lynk_Former]

Here's the code I'm using...

<?php

$print_grab = fread(fopen($HTTP_REFERER, 'r'), 100000);

if ($print_grab) {
$print_start = strpos($print_grab, '<!-- CONTENT START -->');
$print_finish = strpos($print_grab, '<!-- CONTENT END -->');
$print_length = $print_finish-$print_start;
$print_code = Substr($print_grab, $print_start, $print_length);
}

?>

It's supposed to grab code from a referer page and put it into the printer friendly version. It works... well half the time. So far it only works on certain smaller pages but NOT on larger pages.

Got any ideas why that is?...

Have you tried increasing the 100000-byte limit?

[Lynk_Former]

yes I have tried that but it has no affect.

Welcome to WebmasterWorld, Lynk_Former.

Another problem may be the variable itself. HTTP_REFERER is not a reliable variable as it can be spoofed and it is not always present.

You could get away with the whole problem using (x)html/css. This way you can specify a dedicated stylesheet for print using the @media directive ;)
