PHP Migration Problem

[jevansnc]

I have a script that worked great on an old server that I am migrating my sites from. This is screen scraping script that I use. The old version of PHP 4.1, new version is 4.3+. The script is:
########################################
$url = "http://www.domain.com";
$unique_start = "Starting Text";
$unique_end = "Ending Text";

ini_set('max_execution_time', '0');
flush ();
$fd = fread(fopen("$url", "r"), 100000);

if ($fd)
{
$start= strpos($fd, "$unique_start");
$finish= strpos($fd, "$unique_end");
$length= $finish-$start;
$code=substr($fd, $start, $length);
}

$code = str_replace("Some Text", "New Text", $code);

echo $code;
flush ();
#####################################

Can anyone tell me why this script is just outputting empty pages on the new server? Any help would be greatly appreciated. Thank you.

Probaly short tags like <? being used instead of <?php and register globals on the new server being turned off (as all newer version are by default). Showing some code that used to work especially with the opening tags either <? or <?php

I tried the long tags "<?php" and register_globals is on. Neither is working. As I state I have errors turned on as well. It is almost like the script is printing an empty variable and nothing is getting to the variable properly.

Before the line of code if($fd) try echoing out to screen the value of $fd and see if it is what you expect.
